Find all real values of t that satisfy the equation t^2 = 324. If you find more than one, then list your values in increasing order, separated by commas.
Take the square root of both sides
t = +/- 18
t = -18, 18
We know that \(t^2=324\), so we can solve for, \(t \) which is \(18\), and t can also be equal to -18, because any negative number squared, will be positive!
