Solve the equation using square roots. x2 + 10 = 9
Oksana_A [137]
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: <span>B. no real number solutions</span>
