Equation $x^2+4x+2$ is converted to $1(x-(-2))^2-2$

<u>Step-by-step explanation:</u>

We need to complete the square to transform the expression x^2+4x+2 into the form a(x-h)^2+k . Let's do this :

We have , following equation to convert as :

⇒ $x^2+4x+2$

⇒ $(x+2)^2-2$

⇒ $1(x+2)^2-2$

⇒ $1(x-(-2))^2-2$

Comparing this to equation a(x-h)^2+k we get :

$a=1\\h=-2\\k=-2$

Therefore , Equation $x^2+4x+2$ is converted to $1(x-(-2))^2-2$ .
