Question

solutions to f(x) = x^3 + 8x^2 + 15x - 70 using synthetic division

Answer 1

I know one of the answers is 2. Idon't know the others

Answer 2

you mean you want to factor it right ?

Answer 3

no I mean I need the solutions to it. You may have to use the quadratic formula actually. But is that possible having - 70 at the end?

Answer 4

=>x^3 + 10x^2 -2x^2 +35x - 10x -70
=>x^3+10x^2 +35x - 2x^2-20x -70
=>x(x^2 +10x + 35) -2(x^2 +10x + 35)
=>(x-2)(x^2 +10x + 35)

piece of cake from here now! ;)

Answer 5

Oh i see what you mean now. Thank you so much!
