Solve the equation by completing the square. round to the nearest tenth.
x^2 + 8x = 10

a. 1.1, 9.1
b. 1.1, -9.1
c. -1.1, 9.1
d. -1.1, -9.1

 The correct option is (B) 1.1, -9.1.

Step-by-step explanation:  We are given to solve the following quadratic equation by the method of completing the square.

In completing the square method, we need to make left hand side of the above given equation as a perfect square trinomial.

From equation (i), we have

Rounding to the nearest tenth, we get

Thus, the required solution is x = 1.1, -9.1.

Option (B) is CORRECT.
