Answer:

(-3, -4)

Step-by-step explanation:

we have

y=-x^{2} -x+2 ----> equation A

y=2x+2 ----> equation B

equate equation A and equation B

-x^{2} -x+2=2x+2

-x^{2} -x+2-2x-2=0

-x^{2} -3x=0

x(x+3)=0

The solutions of the quadratic equation are x=0 and x=-3

Find the values of y

For x=0

y=2(0)+2=2

For x=-3

y=2(-3)+2=-4

therefore

The solutions of the system are the points (0,2) and (-3,-4)
