Question

use algebra tiles to find $(-4x^{2}-2x - 6)-(-6x^{2}+9)$. combine like terms. for example, write 3 instead of $1 + 1 + 1$.

Explanation:

Step1: Rewrite subtraction as addition

$(-4x^2 - 2x - 6) + (6x^2 - 9)$

Step2: Combine $x^2$ terms

$-4x^2 + 6x^2 = 2x^2$

Step3: Keep the $x$ term

$-2x$ (no like terms to combine)

Step4: Combine constant terms

$-6 - 9 = -15$

Step5: Combine all simplified terms

$2x^2 - 2x - 15$

Answer:

$2x^2 - 2x - 15$
