Plus or minus 12

Step-by-step explanation:

You can indeed use the quadratic formula (a = 3, b = 0, c = -432), but that'd be overkill.  Instead, simplify the given 3y^2 = 432 by dividing both sides by 3:  y^2 = 144.  Next, take the sqrt of both sides, remembering to preface your answers by "plus or minus:"  y = plus or minus sqrt(144) = plus or minus 12.
