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

⇒ 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.
