Question

subtract $7x - 9$ from $2x^2 - 11$.
$\bigcirc$ $2x^2 - 7x - 20$
$\bigcirc$ $2x^2 - 7x - 2$
$\bigcirc$ $2x^2 + 7x - 20$
$\bigcirc$ $2x^2 + 7x - 2$

Explanation:

Step1: Set up subtraction expression

$2x^2 - 11 - (7x - 9)$

Step2: Distribute the negative sign

$2x^2 - 11 - 7x + 9$

Step3: Combine constant terms

$2x^2 - 7x + (-11 + 9)$
$2x^2 - 7x - 2$

Answer:

2x²−7x−2
