Question

What are the x-intercept(s) of the graph of y + 20 = x2 − x?

choices:
(−5, 0) and (4, 0)

(5, 0) and (−4, 0)

(−5, 0) and (−4, 0)

(5, 0) and (4, 0)

Answer 1

To get the x-intercepts, plug in y=0 into the equation.

Answer 2

Soo... 0 +20=x^2-x? @allank

Answer 3

Yes! Continue...

Answer 4

I got x=-4,5
