Question

What are the x-intercepts of the quadratic function f(x)=x^2x-35 ?

A.-7 and 5

B.5 only

C.-5 only

D.7 and -5

Answer 1

I believe your initial equation f(x)=x^2x-35 , should be: f(x)=x²+2x-35

If so, then the x intercepts are the root of this quadratic equation that is

x' =5 & x" = -7 (A)
