A. Plus or minus the square root of 1.

B. no real number solutions

C. 1

D. –1

Answer 1

no real number solutions

Explanation:

Answer 2

`x^2 + 10 = 9`

Subtract 10 from both sides.


`x^2 = -1`

Since the square of a number, x, equals a negative number, -1, the answer cannot be a real number because the square of a real number is always non-negative. Therefore, there is no real number solution to this equation.

Answer: B. no real number solutions
