Question

What are the x-intercept(s) of the graph of y + 30 = x^2 + x?

a. (−5, 0) and (6, 0)

b. (−5, 0) and (−6, 0)

c. (5, 0) and (−6, 0)

d. (5, 0) and (6, 0)

Answer 1

To find x intercept just put y=0,
you get x^2+x-30=0,
x^2+6x-5x-30=0,
x(x+6)-5(x+6)=0
(x+6)(x-5)=0,x=-6or x=5

Answer 2

TY I see now.
