Which shows the correct substitution of the values a, b, and c from the equation -2 = -x + x? - 4 into the quadratic
formula?
Quadratic formula: x =
1-
bb3 - 4 ac
20
0 x= -(-1)#V(-1)2 - 4(1)(-4)
2(1)
x =
= -1/12 - 4(- 1)(-4)
21-1)
x= -18V (1)2 - 42 – 1) – 2)
2(-1)
x= -(- 1) = (-1)3 – 4(1)(= 2)
2(1)
