Factor the expression <br> 5x^2 -22x -15

Murljashka [212]

$5x^2-22x-15=5x^2\underbrace{-25x+3x}_{-22x}-15\\\\=(5x^2-25x)+(3x-15)=5x(x-5)+3(x-5)\\\\=\boxed{(x-5)(5x+3)}$

2(x + 1) – (–x + 5) ≤ –18.

pshichka [43]

You posted twice.

I already answered

2(x + 1) – (–x + 5) ≤ –18

2x + 2 + x - 5 <= -18

3x - 3 <= -18

3x <= -18 + 3

3x <= -15

x <= -15/3

x <= -5
