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?
Quadratic formula: x =
O 2 ± √(-2)²-4(1)(− 3)
2(1)
O
-b± √b²-4ac
2a
-2 ± √(-2)²-4(1)(-3)
2(1)
2+√-2²-4(1)(-3)
2(1)
-2±√-2²-4(1)(-3)
2 (1)
