Question

what are the x- intercepts of the graph of y + 20 = x^2 - x

Answer 1

when y=0 you have 0 + 20 = x^2 - x

so you have 0 = x^2 -x -20 can you solve this

Answer 2

Does It factor to (x-5) (x+4) so the solutions are 5 and -4?

Answer 3

that is right when x = 5 and when x = -4

Answer 4

Thank you

Answer 5
