Hey there!
[tex] 4x^{2} +20x -24[/tex]
We can first factor out the 4 (bring it outside the parenthesis)
[tex]4( x^{2} +5x - 6)[/tex]
Now have a closer look between the parenthesis, because this expression can be factored as well. We're looking for two different numbers with a product of -6 and a sum of 5. Hence, we find the numbers 6 and -1
[tex]4(x-1)(x+6)[/tex]
~ Hope this helps you!
