Solve the equation using square roots. x2 + 10 = 9 a. plus or minus the square root of 1. b. no real number solutions c. 1 d. –1

Subtract 10 from both sides.



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.

B. no real number solutions
