Sergey is solving 5x2 + 20x – 7 = 0. Which steps could he use to solve the quadratic equation by completing the square? Select three options.5(x2 + 4x + 4) = –7 + 20x + 2 = 5(x2 + 4x) = 75(x2 + 4x + 4) = 7 + 205(x2 + 4x) = –7
Answer
A
5(x2 + 4x + 4) = –7 + 20B
x + 2 =C
5(x2 + 4x) = 7D
5(x2 + 4x + 4) = 7 + 20E
5(x2 + 4x) = –7
