# Which of the following statements describes one part of completing the square for x^{2} + 4x = 32?

Take the square root of 36 and add 2

Take the square root of 32 and subtract 2

Take the square root of 36 and subtract 2

Take the square root of 32 and add 2

**Solution:**

Given: Equation is x^{2} + 4x = 32

Now add 4 on both sides for completing the square.

x^{2} + 4x + 4 = 32 + 4

x^{2} + 4x + 4 = 36

So we get,

(x + 2)^{2} = 36

Taking square root on both sides

√(x + 2)^{2} = √36

We know that

x + 2 = ±6

x + 2 = 6 or x + 2 = 6

x = 6 - 2 or x = -6 - 2

x = 4 or x = -8

Therefore, the statement which describes one part of completing the square is to take the square root of 36 and subtract 2.

## Which of the following statements describes one part of completing the square for x^{2} + 4x = 32?

**Summary:**

The statement which describes one part of completing the square for x^{2} + 4x = 32 is to take the square root of 36 and subtract 2.
