Question

Factor: 4x2 + 4xExpand: -(x – 3)​

Answer 1

Question: Factor: 4x2 + 4x

Find the GCF.

$gcf = 4x$

Factor out the GCF.

$4x( \frac{4 {x}^{2} }{4x} + \frac{ {4x} }{4x} )$

Simplify each term in parentheses.

$4x(x + 1)$

Hence, the answer is 4x(x + 1).

Question: Expand: -(x - 3)

Remove parentheses.

$- x + 3$

Regroup terms.

$3 - x$

Therefor, the answer is 3 - x.
