Question

Which model represents the factors of 4x2 - 9?

Answer 1

Its c

Explanation:

Answer 2

The factors are
`(2x-3)(2x+3)`

Explanation:

Subtraction of perfect squares:

The factorization of the subtraction of perfect squares is given by:

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

In this question:

`4x^2 - 9 = (2x)^2 - 3^2`

So

`(2x)^2 - 3^2 = (2x-3)(2x+3)`

The factors are
`(2x-3)(2x+3)`
