Answer:
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)
