Answer:
x=2, x=-1
Step-by-step explanation:
f(x) = x^2 − x − 2
Set equal to zero
0 = x^2 − x − 2
Factor
What 2 numbers multiply to -2 and add to -1
-2*1 = -2
-2+1 =1
0=(x-2) (x+1)
Using the zero product property
x-2 =0 x+1 =0
x=2 x=-1

this is using only the graph and not the text provided above. hopefully the graph is right :P
X^2 + x = 42
sum indicates addition
a number = x
it's square = x^2
