PLEASE HELP!!! <br> Solve the quadratic equation by completing the square.

kow [346]

The values of x in the quadratic equation using completing the square method are $x=-4 \pm \sqrt{5}$ .

Given information:

The quadratic equation is $x^2+8x+11=0$ .

It is required to factorize the given quadratic equation using completing the square method.

<h3>How to factorize a quadratic equation?</h3>

Use completing the square method to solve the equation as,

$x^2+8x+11=0\\(x)^2+2(x)(4)+4^2-4^2+11=0\\( (x)^2+2(x)(4)+4^2)-4^2+11=0\\(x+4)^2-16+11=0\\(x+4)^2=5\\(x+4)=\pm \sqrt{5} \\x=-4 \pm \sqrt{5}$

Therefore, the values of x in the quadratic equation using completing the square method are $x=-4 \pm \sqrt{5}$ .
