\frac{1}{7}-\left(y\times \frac{1}{7}-y^{2}\right)
Use the distributive property to multiply y by \frac{1}{7}-y.
\frac{1}{7}-y\times \frac{1}{7}-\left(-y^{2}\right)
To find the opposite of y\times \frac{1}{7}-y^{2}, find the opposite of each term.
\frac{1}{7}-\frac{1}{7}y-\left(-y^{2}\right)
Multiply -1 and \frac{1}{7} to get -\frac{1}{7}.
\frac{1}{7}-\frac{1}{7}y+y^{2}
The opposite of -y^{2} is y^{2}.
\frac{1}{7}-\left(y\times \frac{1}{7}-y^{2}\right)
