Question

combine like terms means to add the coefficients (numbers) in front of like variables (letters). use the sketch area if needed. combine the like terms and submit your answer. *start with the $x^{2}$ terms first, then combine your xs, and your constant term last! -3 + 7x^{2}-4x - 5+3x^{2}-2x

Explanation:

Step1: Combine $x^{2}$ terms

$7x^{2}+3x^{2}=(7 + 3)x^{2}=10x^{2}$

Step2: Combine $x$ - terms

$-4x-2x=(-4-2)x=-6x$

Step3: Combine constant terms

$-3 - 5=-8$

Step4: Write the final expression

$10x^{2}-6x - 8$

Answer:

$10x^{2}-6x - 8$
