Question

Solve each quadratic equation. a^2 + 2a - 3 = 0

Answer 1

a=1,-3

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

Answer 2

y=(a+2)(a-1)

Explanation:

sum - +2

product - -3

factors - +2, -1

y=(a+2)(a-1)

x intercepts will be -2, +1
