Question

What are the roots of? PLEASE HELP >>>y=4x^2-20x-24

Answer 1

you can start by factoring the four out of each term

Answer 2

First, factorize the right hand side equation in x by middle term:

4x^2 - 20x -24
= 4x^2 - 24x + 4x - 24
= 4(x+1)(x-6)

Now, find the value of x if y was 0 (from the equation:

y=4(x+1)(x-6)

Those will be your roots
