Question

What are the x-intercept(s) of the graph of y − x2 = 11x + 30?

Answer 1

You're gonna have to solve the quadratic.
\[y - x^{2} = 11x + 30\]
\[y = x^{2} + 11x + 30\]
Substitute y for 0.
\[0 = x^{2} + 11x + 30\]
Can you solve the quadratic now?

Answer 2

i subtract x^2 right?

Answer 3

Now. You have to factor it.

Answer 4

oh alright, i ended up with x= -6,-5... so its (-5,0) and (-6,0)?

Answer 5

Yup :)

Answer 6

alright thanks!
