Question

How do you factor `16x^2-36` using the difference of squares?

Answer 1

`16x^2 - 36` is the difference of two squares and will always factor in the following pattern: `x^2 - y^2 = (x + y)(x - y)`

The perfect square of `16x^2` is `4x`
The perfect square of 36 is 6

`16x^2 - 36` = (4x + 6)(4x - 6)
