Problem is solved in the picture.

Step-by-step explanation:

Hope this may help!

Answer 2

Answer:

Graph attached

x = -2

x = 1

Step-by-step explanation:

x P(x) = x^2 + x - 2

-5 18

-4 10

-3 4

-2 0

-1 -2

0 -2

1 0

2 4

3 10

4 18

5 28

x² + x - 2  =0

=> x² -x + 2x - 2 = 0

=> x(x - 1) + 2(x - 1) =0

=> (x + 2)(x - 1) =0

=> x = -2  & x = 1
