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

Answers

B.
1.1, -9.1

x^(2) +8x=10

Answer:  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.

x^2+8x=10~~~~~~~~~~~~~~~~(i)

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

x^2+8x=10\n\n\Rightarrow x^2+2* x* 4+4^2=10+4^2\n\n\Rightarrow (x+4)^2=10+16\n\n\Rightarrow (x+4)^2=26\n\n\Rightarrow x+4=\pm√(26)\n\n\Rightarrow x=-4\pm √(26)\n\n\Rightarrow x=-4\pm 5.09\n\n\Rightarrow x=-4+5.09,~~~~~x=-4-5.09\n\n\Rightarrow x=1.09,~~~~~~~~~\Rightarrow x=-9.09.

Rounding to the nearest tenth, we get

x=1.1,~~-9.1.

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

Option (B) is CORRECT.
