Sergey is solving 5 x squared plus 20 x minus 7 is equal to 0 Which steps could he use to solve the quadratic equation by completing the square? Choose three correct answers.

Move −7 to the right side to get 5(x² + 4x) = 7, which is choice E. To complete the square, add 4 inside the parentheses; because the expression is multiplied by 5, this adds 20 to the right side, giving 5(x² + 4x + 4) = 7 + 20, or choice B. Then divide by 5 and take square roots: (x + 2)² = 27/5, so x + 2 = ±√(27/5), as in choice A.
