Solve the given quadratic equation. x^2=121

x = 11

Step-by-step explanation:

You are solving for x. Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x, by rooting both sides:

√(x²) = √(121)

x = √121

x = √(11 * 11)

Note that when you have two of the same number multiplied within the root, they are squared, which makes them into a whole number.

x = √11 * √11 = 11

x = 11 is your answer.
