What number should be added to both sides of the equation to complete the square? x2 – 6x = 5

Answer not available

Bao Yu is completing the square to solve the polynomial equation.x2 – x – 3 = 0

adding –x to both sides of the equation

adding –3 to both sides of the equation

isolating the first term, x2

isolating the constant, –3
