Question

What are the x-intercepts of the quadratic function y=x^2-x-2

Answer 1

(-1,0) et (2,0)

Explanation:

Facteur: (x + 1) (x-2) = 0

une des équations
`(x1 + x2) = 0.`

-1 et -2 font 0, alors ils sont x

Answer 2

(-1,0) and (2,0)

Explanation:

Factor to get (x+1)(x-2)=0

Make at least one of the (x1+x2) equations equal 0.

-1 and -2 make them 0, so they are the x intercept.
