Answer:

a=1,-3

Step-by-step explanation:

You would use the quadratic formula to get A and then if you wanted to check yourself you could plug back in and see if it equals 0

1^2+2(1)-3=0

(-3)^2+2(-3)-3=0

They are both true and both equals 0 so your answers would be a= 1,-3

Hope this is Helpful
