The answer would be answer choice d. The above answer
Answer:
The answer is -a^2 + 3a +1
Let me know if it's right, this is what I got when I did the problem :)
X^2 - 7x + 12 = 0
x^2 - 4x - 3x + 12 = 0
x (x - 4) -3 ( x - 4) = 0
(x - 4) (x - 3) = 0
x = 3 , 4
Check the answer by plugging in 3 and 4 for x, if the equation equals zero then you have your answer.
