Solve for y.3y^2=432 Enter your answers in the boxes.y = or y =

Answer 1

The given equation is:

`3y^2=432`

Divide both sides of the equation by 3:

`\begin{gathered} (3y^2)/(3)=(432)/(3) \\ y^2=144 \end{gathered}`

Therefore,

`\begin{gathered} y=\pm√(144) \\ y=\pm12 \end{gathered}`

Hence

y = -12 or y = 12
