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.

1-cos^2 A / sec^2 A - tan^2 A
tiny-mole [99]
I hope this helps you



✔cos^2A+sin^2A=1


✔1-cos^2A=sin^2A

✔cos2A=cos^2A-sin^2A

✔sin2A=2.sinA.cosA


secA=1/cosA


tgA=sinA/cosA


sin^2A/1/cos^2A-sin^2A/cos^2A


sin^2A.cos^2A/cos2A

2.sin^2A.cos^2A/cos2A


sin2A.2.sin2A/cos2A
