Question 1021784: I am 73 years old and have forgotten more about math than I ever used.
Am I correct in saying : X squared + 1 = 10 X = 3 Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! x^2 + 1 = 10
:

:
take square root of both sides of =
:
x = 3 or x = -3
:
note that 3 * 3 = 9 and -3 * -3 = 9, where * means Multiply
