Solve this problem out

Answer 1

Solving the equation $2x^2-12x+6=0$ using completing square method we get $(x+3)^2=6$

So, Option A is correct.

Step-by-step explanation:

We need to solve the equation $2x^2-12x+6=0$ using completing square method.

Solving using completing square method

$2x^2-12x+6=0$

For completing the square we need to make formula a^2-2ab+b^2=(a-b)^2

Divide the equations by 2

$x^2-6x+3=0$

$x^2-6x+3=0$

Adding and subtracting (3)^2 on both sides.

$(x)^2-2(x)(3)+(3)^2-9+3=0$

$(x+3)^2-6=0$

$(x+3)^2=6$

Solving the equation $2x^2-12x+6=0$ using completing square method we get $(x+3)^2=6$

So, Option A is correct.
