Question

What are the x-intercept(s) of the graph of y + 12 = x2 + x?

(4, 0) and (3, 0)

(4, 0) and (−3, 0)

(−4, 0) and (−3, 0)

(−4, 0) and (3, 0)

Answer 1

For finding x intercept simply put y = 0..

Answer 2

So, put y = 0:
\[12 = x^2 + x\]

\[x^2 + x - 12 = 0\]

Can you factorize it now ??

Answer 3
