Match the quadratic functions with their a, b, and c values
b = -12
b = 6
c = -2
a = -1
b = -5
c = -3
a = 1
b = -8
c = 10
c = 1
b = -4
b = 4
b = 10
c = -20
b = 7
c = -11
c = -36
c = -18
x2 + 10x – 2 = 0
x2 – 11 = 4x
x2 – 8x = 20
x2 – 5x – 36 = 0
x2 + 6x + 10 = 0
-x2 – 12x – 18 = 0
-x2 + 7x – 3 = 0
x2 + 4x + 1 = 0
Match the quadratic functions to their first step in solving with the quadratic formula
