Question

What number should be added to both sides of the equation to complete the square?

x2 – 6x = 5

Answer 1

x² - 6x + __ = 5 + __

to complete the square, you take your "middle" value, divide it by 2, then square it. in this case:

-6/2 = -3
(-3)² = 9

9 is the number you'd add to both sides to complete the square.
x² - 6x + 9 = 5 + 9

Answer 2

The equation x^2 - 6x = 5 is a quadratic function, and we add 9 to both sides of the equation to complete the square

What is the completing the square?

The completing the square method of solving a quadratic function is a way of expressing the quadratic function as a perfect square

The equation is given as:

x^2 - 6x = 5

Take the coefficient of x

k = -6

Divide by 2

k/2 = -3

Square both sides

(k/2)^2 = 9

This means that we add 9 to both sides of the equation
