Answer:
Step-by-step explanation:
[tex]x^3+2x^2-15x=x(x^2+2x-15)=x(x^2+5x-3x-15)\\\\=x(x(x+5)-3(x+5))=x(x+5)(x-3)[/tex]
Answer:
c x( x+5) (x-3)
Step-by-step explanation:
x^3 + 2x^2 - 15x
First factor out the greatest common factor x
x( x^2 + 2x - 15)
What 2 numbers multiply together to give us -15 and add together to give us 2
5*-3 = -15
5+-3 = 2
x( x+5) (x-3)
