Simplify 3(x - 2) + 2(2x + 5) - x.
6x + 4
5x + 1
7x + 1
4x + 6
Distribute: 3x - 6 + 4x + 10 - x = (3x+4x-x) + (4) = 6x + 4. See step-by-step here.
Combine like terms in 5x^2y - 3xy^2 + 7x^2y - xy^2.
12x^2y - 4xy^2
2x^2y - 2xy^2
5x^2y + 7x^2y - 4xy^2
12x^2y + 4xy^2
Combine x^2y: 5+7 =12 and combine xy^2: -3-1 = -4, giving 12x^2y - 4xy^2. More info here.
Simplify (3x + 1)(x - 4) + 2(x^2 + 2x).
5x^2 - 7x - 4
3x^2 - 11x - 4
5x^2 + x - 4
3x^2 - 7x - 4
First expand: 3x^2 -12x + x -4 = 3x^2 -11x -4, then add 2x^2 + 4x gives 5x^2 -7x -4. Review FOIL and distribution here.
Expand and simplify (x + 2)(x^2 - 2x + 4).
x^3 + 8
x^3 + 2x^2 - 4x + 8
x^3 - 4x + 8
x^3 + 2x^2 + 8
Distribute: x*(x^2 -2x +4) + 2*(x^2 -2x +4) = x^3 -2x^2 +4x +2x^2 -4x +8 = x^3 +8. See sum of cubes form here.

Cheat Sheet

  1. Combine Like Terms Efficiently -

    Combining like terms is the first step when you simplify this polynomial, since terms with the same variable and exponent add directly. Group x² terms, x terms, and constant terms to streamline your simplification, using the mnemonic "same base, same place." According to Khan Academy, this strategy is essential for mastering simplify polynomial expressions.

  2. Master the Distributive Property -

    Applying the distributive property a(b + c) = ab + ac helps break down complex polynomial chunks before you simplify polynomial expressions. This skill is critical when you face nested parentheses in algebra polynomial simplification. Per MIT OpenCourseWare, clear understanding of distribution reduces errors and speeds up your work.

  3. Leverage Exponent Rules -

    Remember that when multiplying like bases you add exponents and when dividing you subtract them (x^m · x^n = x^(m+n)). This rule is fundamental for polynomial expression practice involving powered terms. As noted by the National Council of Teachers of Mathematics, exponent laws prevent common mistakes in combining like terms quiz scenarios.

  4. Follow the Order of Operations (PEMDAS) -

    Before combining like terms or applying the distributive property, ensure you respect Parentheses, Exponents, Multiplication/Division, and Addition/Subtraction. This sequence avoids missteps and aligns with Common Core State Standards for algebraic simplification. Consistent practice with PEMDAS boosts your confidence in every step of algebra polynomial simplification.

  5. Practice with Targeted Quizzes -

    Engage in a combining like terms quiz or polynomial expression practice to reinforce each concept in real time. Websites like IXL and MathStackExchange offer free drills that mirror classroom challenges and provide instant feedback, perfect for anyone wanting to simplify this polynomial effectively. Frequent practice solidifies your skills and makes mastering simplify polynomial expressions feel effortless.
