To solve the equation
by completing the square, follow these steps:### Step 1: Move the constant term to the other side of the equation
### Step 2: Complete the squareTo complete the square, we need to add and subtract the square of half the coefficient of
. The coefficient of
is 12, so half of it is 6, and its square is
.Add and subtract 36 on the left side:
So, the equation in the form \((x + D)^2 = E\) is:
### Step 3: Solve the equationTake the square root of both sides:
Solve for
:
### Final AnswersA) The equation
is equivalent to:
B) The solutions to the equation are:
