Question

Hi really need some help!

Answer 1

Answer:
`(5x+12)(5x-12)`

Explanation:

`25x^2-144`

What we have here is;

`a^2-b^2`

This is as simple as extracting the square root of both terms and multiply them by themselves, one being positive and the other negative as following;

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

-----------------------------------------------------------------

The square root of 25 is 5,
`x^2` is x, and 144 is 12

`25x^2-144=(5x+12)(5x-12)`
