Question

Find the x intercepts,
y=x^2-4x-5
are they (-5,0),(1,0)?

Answer 1

x intercepts means y=0

Answer 2

x^2-4x-5=0
(x-5)(x+1)=0

Answer 3

So either
x-5=0
x+1=0
Solve each of these to get your answer

Answer 4

it's actually the opposite signs of those

Answer 5

Ok so it would be x=5, and x=-1
i

Answer 6

yup

Answer 7

Did I type hem in the right way the first time? Just opposite numbers

Answer 8

Awesome Thank you so much!! I really appreciate it!!
