Question

Rhett is solving the quadratic equation 0= x2 – 2x – 3 using the quadratic formula. Which shows the correct substitution of the values a, b, and c into the quadratic formula?

Answer 1

its A

Explanation:

just did it on edge

Answer 2

I presume that x2 means "x squared"
a and b are the coefficients of x squared and x
c is the constant. So for this the values are:
a = 1 (because "x squared" is really "one x squared")
b = 2 (in front of the "x")
c = -3 (the constant)
