Which of the following is an equivalent equation obtained by completing the square of the expression below? x^2+6x−8=0 A (x+3)^2=8 B (x+3)^2=17 C (x+3)^2=1 D x^2+6x+6=14

Solving the equation by completing the square method we get

Option B is correct option.

Step-by-step explanation:

We need to solve the equation by completing the square method.

For completing the square method: we need to follow:

We are given:

Solving by completing the square

We need to find ? in our case ? is 3 because 2*3= 6 and our middle term is 6x i,e 2(x)(3)=6x.

So, adding and subtracting (3)^2

So, solving the equation by completing the square method we get

Option B is correct option.

14

step-by-step explanation:

14 x 3 = 42
