Question

I need help finding out if i have to factor this using GCF or the other way and why ? pls helpp

Answer 1

Explanation:

This is the difference of squares. There is no GCF to take out.

The first term is a "perfect square" and so is the second term

You can take the square root of both terms perfectly

`\sqrt{4w^(2) }` = 4w

√1 = 1

format for factors:

(√ of 1st term + √ of 2nd term)(√ of 1st term - √ of 2nd term)

The order of + and minus doesn't matter which parenthesis it goes in

factor:

(4w+1)(4w-1)
