Solve the quadratic equation by using either a numeric or a graphic approach, x² + 2x-3-0
x= -1.1 or x = -2
C. x = 2 or x = 5
b. x = 2.3 or x = -0.82
dx= 1 or X=-3

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
