Which of the following is a binomial expression?
3x + 4
x^2 + 3x + 2
5x
7
A binomial consists of exactly two terms separated by a plus or minus sign. '3x + 4' has two terms, making it a binomial expression.
What does the 'F' in the FOIL method stand for when multiplying binomials?
First
Final
Factor
Fibonacci
FOIL stands for First, Outer, Inner, Last. The 'F' specifically represents the multiplication of the first terms of each binomial.
After using the FOIL method to expand two binomials, what is the next step?
Combine like terms
Subtract the inner terms
Multiply only the first and last terms
Divide by the coefficient
Once the FOIL method is applied, four terms are produced. The next step is to combine like terms to simplify the expression.
Which binomial represents the difference of two terms?
x - 5
x + 5
x^2 - 5x + 6
3x
A binomial showing subtraction between two terms, like x - 5, clearly represents a difference. The minus sign indicates the subtraction of one term from another.
What is the expanded form of (x + 3)(x + 2) using the FOIL method?
x^2 + 5x + 6
x^2 + 6x + 5
x^2 + 3x + 2
x^2 + 3
Using FOIL, (x + 3)(x + 2) multiplies to x*x (x^2), x*2 (2x), 3*x (3x), and 3*2 (6). Combining the middle terms yields x^2 + 5x + 6.
What is the expanded form of (2x - 3)(x + 4)?
2x^2 + 5x - 12
2x^2 + 8x - 12
2x^2 - 7x - 12
2x^2 + x - 12
Multiplying (2x - 3)(x + 4) using FOIL gives 2x*x = 2x^2, 2x*4 = 8x, -3*x = -3x, and -3*4 = -12. Combining like terms, 8x - 3x results in 5x, so the answer is 2x^2 + 5x - 12.
What is the expanded form of (x + 5)^2?
x^2 + 10x + 25
x^2 + 25
x^2 + 5x + 25
x^2 + 2x + 25
The square of a binomial (x + 5)^2 is expanded as x^2 + 2·5·x + 5^2, which simplifies to x^2 + 10x + 25.
What is the result of multiplying the binomial (3x - 2) by its conjugate (3x + 2)?
9x^2 - 4
9x^2 + 4
9x^2 - 2
9x^2 + 2
Multiplying a binomial by its conjugate uses the difference of squares formula: (a - b)(a + b) = a^2 - b^2. Here, a = 3x and b = 2, so the product is 9x^2 - 4.
How many terms are produced when initially expanding the binomials (x + 2)(x - 3) using the FOIL method?
4 terms
2 terms
3 terms
5 terms
The FOIL method multiplies each term in the first binomial with each in the second, initially producing four terms. These are later combined if like terms are present.
What is the constant term in the expansion of (2x - 3)(x + 5)?
-15
10
5
15
The constant term is obtained by multiplying the constant terms from each binomial. In this case, (-3) × 5 equals -15.
Simplify the expression: (x + 4)^2 - (x - 2)^2.
12x + 12
12x - 12
x^2 + 12
8x + 20
Expanding (x + 4)^2 gives x^2 + 8x + 16 and (x - 2)^2 gives x^2 - 4x + 4. Subtracting the second from the first cancels x^2, leaving 12x + 12.
If (x + p)^2 expands to x^2 + 14x + 49, what is the value of p?
7
14
49
-7
Comparing (x + p)^2 = x^2 + 2px + p^2 with x^2 + 14x + 49, we equate 2p to 14 and p^2 to 49, which gives p = 7.
Which factorization correctly represents the quadratic expression x^2 + 7x + 10?
(x + 5)(x + 2)
(x + 7)(x + 1)
(x + 10)(x - 3)
(x + 4)(x + 3)
The factors of 10 that sum to 7 are 5 and 2, so the quadratic factors as (x + 5)(x + 2).
Which property is primarily used when applying the FOIL method to multiply binomials?
Distributive property
Commutative property
Associative property
Reflexive property
The FOIL method is essentially an application of the distributive property, where each term of one binomial is distributed to every term of the other.
What is the product of the binomials (x - 3)(x + 7)?
x^2 + 4x - 21
x^2 + 10x - 21
x^2 - 4x - 21
x^2 - 10x - 21
Multiplying (x - 3)(x + 7) via FOIL yields x^2 (First), 7x (Outer), -3x (Inner), and -21 (Last). Combining 7x and -3x gives 4x, so the result is x^2 + 4x - 21.
Using the Binomial Theorem, find the coefficient of x^3 in the expansion of (2x - 1)^5.
80
40
16
32
In the expansion of (2x - 1)^5, the term containing x^3 occurs when the exponent of (2x) is 3. This happens when k = 2 in the Binomial Theorem, giving C(5,2)·(2^3)·(-1)^2 = 10·8·1 = 80.
Determine the constant term in the expansion of (x + 2/x)^6.
160
80
64
120
For (x + 2/x)^6, the general term is C(6,k)·x^(6-k)·(2/x)^k = C(6,k)·2^k·x^(6-2k). Setting the exponent 6-2k to zero gives k = 3, and the constant term is C(6,3)·2^3 = 20·8 = 160.
In the expansion of (1 + x)^n, the third term is given by C(n,2)x^2. If x = 1 and this term equals 45, what is the value of n?
10
9
11
8
With x = 1, the third term in (1 + x)^n is C(n,2) = n(n-1)/2. Setting n(n-1)/2 equal to 45 gives n(n-1) = 90, which is satisfied when n = 10.
Given that (ax + b)^2 expands to 16x^2 + 24x + 9, find the values of a and b.
a = 4, b = 3
a = 4, b = -3
a = -4, b = 3
a = -4, b = -3
Expanding (ax + b)^2 gives a^2x^2 + 2abx + b^2. Equating coefficients with 16x^2 + 24x + 9, we have a^2 = 16 and b^2 = 9. Assuming positive values, a = 4 and b = 3, which also satisfies 2ab = 24.
Solve for x: If (x + 2)² = (x - 3)², what is the sum of the distinct solutions?
0.5
5
0
1
Setting (x + 2)² equal to (x - 3)² leads to the equation (x + 2)² - (x - 3)² = 0, which factors as 5(2x - 1) = 0. Solving gives x = 0.5, the only distinct solution.
