What are the solutions to the equation [tex]x^2 = 169[/tex]?

Choose all answers that are correct.

x 2 = 169 ∣ − 169 x 2 − 169 = 169 − 169 x 2 − 1 3 2 = 0 ( x − 13 ) ( x + 13 ) = 0 x − 13 = 0 or x + 13 = 0 x = 13 or x = − 13

Since you are finding what number doubled equals 169 you have to find the square root of 169 which is 13 because 13 times 13 equals 169

The solutions to the equation x 2 = 169 are x = 13 and x = − 13 . These represent the two possible values of x that satisfy the equation, as both positive and negative values yield the same squared result. Whenever dealing with squared terms, always remember to consider both the positive and negative roots.
