Question

Factor: 4x2 + 4x
Expand: -(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.
