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?
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)
