Question

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:

$\begin{gathered} \frac{3y^2}{3}=\frac{432}{3} \\ y^2=144 \end{gathered}$

Therefore,

$\begin{gathered} y=\pm\sqrt{144} \\ y=\pm12 \end{gathered}$

Hence

y = -12 or y = 12
