Question

Find the x-intercept of x^4+5x^3+4x^2???? Please help :)

Answer 1

Factor out x^2 first.
Then equate it to zero and solve for x.

Answer 2

So do you mean (x^2+4x)(x^2+x)?

Answer 3

y = x^4+5x^3+4x^2 = x^2(x^2 + 5x + 4)
Factor the quadratic: y = x^2(x+4)(x+1)
x-intercept is when y = 0
x^2(x+4)(x+1) = 0

Solve for x.

Answer 4

Oh. Yes it is correct thank you so much :) I though I had to do easy tri, not just simply factor it lol

Answer 5

you are welcome.
