Label exact values for all x and y intercepts.

Question

Q1:
f(x)=x^3-2x^2-5x+10
f(x)=X^2(x-2)-5(x-2)
f(x)=(x-2)(x^2-5)
f(x)=(x-2)(???)

Q2:
f(x)=x^4-5x^2
f(x)=x^2(x^2-5)
f(x)=???

please help and thank you

Answer 1

1) (x-2)(x-sqrt5)(x+sqrt5)
2) same thinking.

Answer 2

what about x^2 in Q2? I'm suppose to graph this. So the x-int is 0? so does that mean the line won't pass through that point?
