1. what are the values of a, b, and c in the quadratic formula given the equation 3x^2-x= 4? a. a=3, b=0, c=-4 b. a=3, b=1, c=4 c. a=3, b=1, c=4 d. a=3, b=-1, c=-4 2. what is the first correct step for solving the equation, x^2+x=12 ?

D. a=3, b=-1, c=-4 and for the next D. a=3, b=-1, c=-4

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
