Helppp plz i need some help

Step-by-step explanation:

x² + 8x + 15

(x²+5x)+(3x+15)

x(x+5) + 3(x+5)

(x+3) (x+5)

You can notify me if you don't understand

x-ints: (-5,0) and (-3,0)

Factors: (x+5)(x+3)

Step-by-step explanation:

First, make the equation equal 0. Then, because x² is x × x, factor it by doing a diamond, so you're seeing what times 15 equals 8, so 3 times 5. The factors would be (x+5)(x+3).

Then, to get the x-ints, put that back into the equation: (x+5)(x+3)=0.

-5 + 5=0   and    -3 + 3=0, so x=-5 and -3, so the x-ints are (-5,0) and (-3,0)

(I got u and hope this helps :P)

they are simplified
