[tex] x^2 + 10 = 9 [/tex]
Subtract 10 from both sides.
[tex] x^2 = -1 [/tex]
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
