Answer:
y=(a+2)(a-1)
Step-by-step explanation:
sum - +2
product - -3
factors - +2, -1
y=(a+2)(a-1)
x intercepts will be -2, +1
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
