What number should be added to both sides of the equations to complete the square? x^2-6x=5
Need help on this one struggling please help?

These expanded squares will help you understand “completing the square”

x^2 + 6x + 9 = (x + 3)^2

x^2 + 10 x + 25 = (x + 5)^2

x^2 – 14x + 49 = (x – 7)^2

Look at the number in front of the x in each of those examples.

If you half that, and then square it you get the number at the end.

To avoid forgetting this tomorrow, just remember this phrase:-

[HALF THE COEFFICIENT OF x] squared.

Of course you have to understand that the number in front of the x term is called the coefficient of x

So, how would that help with your example, with x^2 – 6x on the left side of the equation. Ah yes,

[HALF THE COEFFICIENT OF x] squared.

HALF THE COEFFICIENT OF x is -3, and that number squared. is 9.

So that tells us we add 9 to both sides.

x^2 – 6x + 9 = 5 + 9 = 14

(x – 3)^2 = 14

Take the square root of both sides, (remember plus and minus options).

x = 3 ± √(14)

Intro to equations with variables on both sides (video) | Khan Academy

Intro to equations with variables on both sides (video) | Khan Academy – we have X's on both sides equations we're adding and subtracting numbers how do you solve it now we'll do it a couple of different ways the the important you've solved the equation you can actually go back and check whether that works so what we're gonna do is just do a bunch of operations on both…Add or to both sides. Take the square root of both sides. There is no solution in the real number system. It may interest you to know that the completing the square process for solving quadratic equations was used on the equation ax 2 + bx + c = 0 to derive the quadratic formula.I don't know what this question means ! But if it means to just confine x2 and -6x in a square or to make them part of a square then it could be done as follows. That is the number that should be added to both sides. Adding both sides of equation to complete the square.

Solving Quadratic Equations | Completing the square – Completing the square is done as follows: 1. Write the equation in a way that the constants are in the right side while the terms with x are on the left. x^2 – 6x = 5. 2. Make sure that the coefficient of the x^2 term is 1. x^2 – 6x = 5. 3. Adding a term to both sides that will complete the square in t.Upon completing this section you should be able to solve equations involving signed numbers. Using the same procedures learned in chapter 2, we subtract 5 from each side of the equation Remember, adding the same quantity to both sides of an inequality does not change its direction.to solve by completing the square, what value should be 1 Answer. ? add numbers ?… x^2 +10x+8=0 Would this be never true? both sides of an equation containing fractions can be multiplied by the same number w/o changing the solution of the equation.
