Question

2y^2-11y=0

Answer 1

`2y^2 -11y=0`

`<=> y(2y -11)=0`

\(\Leftrightarrow\left[{}\begin{matrix}y=0\\2y-11=0\end{matrix}\right.\\ \Leftrightarrow\left[{}\begin{matrix}y=0\\2y=11\end{matrix}\right.\\ \Leftrightarrow\left[{}\begin{matrix}y=0\\y=\dfrac{11}{2}\end{matrix}\right.\)

Answer 2

\(2y^2-11y=0\)

\(\Rightarrow y\left(2y-11\right)=0\)

\(\Rightarrow\left[{}\begin{matrix}y=0\\2y-11=0\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}y=0\\y=\dfrac{11}{2}\end{matrix}\right.\)
