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.

t^2=324 

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!
