Hello there!

324 + 36^2 = x^2

324 + 1296 = x^2

1620 = x^2

-x^2 + 1620 = 0

-x^2 = 0 - 1620

-x^2 = -1620

We don't want to leave the variable with a negative sign, so we should divide both sides by -1 to remove the negative sign

-x^2/-1 = -1620/-1

x^2 = 1620

Then take square root

x = +- √1620

x =18√5 or x = -18√5


I hope this helps!
