Jamal solved the equation by completing the square x^2 -8x + 14 = 0 which equation shows one of the steps jamal could have taken to complete the square? a. x^2 - 8x + 16 = -14 b. x^2 -8x + 64 = -14 c. x^2 - 8x + 64 = -14 + 64 d. x^2 - 8x + 16 = -14 + 16

Solve for x:

x^2 - 8 x + 14 = 0

Solve the quadratic equation by completing the square.

Subtract 14 from both sides:

x^2 - 8 x = -14

Take one half of the coefficient of x and square it, then add it to both sides.

Add 16 to both sides:

x^2 - 8 x + 16 = 2 [THIS STEP IS THE SECOND ONE OF YOUR 4 CHOICES]

Factor the left hand side.

Write the left hand side as a square:

(x - 4)^2 = 2

Eliminate the exponent on the left hand side.

Take the square root of both sides:

x - 4 = sqrt(2) or x - 4 = -sqrt(2)

Look at the first equation: Solve for x.

Add 4 to both sides:

x = 4 + sqrt(2) or x - 4 = -sqrt(2)

Look at the second equation: Solve for x.

Add 4 to both sides:

x = 4 + sqrt(2)       or         x = 4 - sqrt(2)

she gotta workk that a 2

step-by-step explanation:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
