What is the easiest way to learn completing the square?
- Step 1 Divide all terms by a (the coefficient of x2).
- Step 2 Move the number term (c/a) to the right side of the equation.
- Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation.

What is the formula to complete the square?
In mathematics, completing the square is used to compute quadratic polynomials. Completing the Square Formula is given as: ax2 + bx + c ⇒ (x + p)2 + constant. The quadratic formula is derived using a method of completing the square. Let’s see.
What number must be added to x2 12x to complete the square?
The value which must be added to the expression x2 + 12x to make it a perfect-square trinomial is 36.
Why do you complete the square?
Completing the Square is a technique which can be used to find maximum or minimum values of quadratic functions. We can also use this technique to change or simplify the form of algebraic expressions. We can use it for solving quadratic equations.
What does it mean to solve by completing the square?
Completing the square means writing a quadratic in the form of a squared bracket and adding a constant if necessary. For example, consider x2 + 6x + 7.
What quantity should be added to both sides of this equation to complete the square?
Take square root on both sides. Therefore, 9 should be added to both sides of the equation to complete the square (x2 – 6x = 5).
Is x2 12x 36 a perfect square?
x2 + 12x + 36 is a perfect square trinomial.
What is the point in completing the square?
Completing the square means writing a quadratic in the form of a squared bracket and adding a constant if necessary. One application of completing the square is finding the maximum or minimum value of the function, and when it occurs.
