Question

Help Please? Factor Completely: 2x2 − 32

Answer 1

Answer:

Option 4th is correct

$2 \cdot (x-4)(x+4)$

Step-by-step explanation:

Using difference of square:

$a^2-b^2=(a-b)(a+b)$

GCF is the largest number that divide the given polynomial or expression.

Given the expression:

$2x^2-32$

We have to completely factor the expression.

GCF of $2x^2$ and 32 is, 2

then;

$2 \cdot (x^2-16)$

Using difference of square

$2 \cdot (x-4)(x+4)$

therefore, the completely factor of $2x^2-32$ is, $2 \cdot (x-4)(x+4)$
