Solution

Identify the term and the coefficient of $y^{2}$ :
The given expression is $2 x^{2} y - 15 x y^{2} + 7 y^{2}$ .
Then, the terms of the given expression are $2 x^{2} y, - 15 x y^{2}$ and $7 y^{2}$ .
So,
The terms containing $y^{2}$ are $- 15 x y^{2}$ and $7 y^{2}$ .
And, the coefficient of $y^{2}$ in $- 15 x y^{2}$ is $- 15 x$
And, the coefficient of $y^{2}$ in $7 y^{2}$ is $7$
Hence, the required terms containing $y^{2}$ are $- 15 x y^{2}$ and $7 y^{2}$ and the coefficients of $y^{2}$ are $- 15 x$ and $7$ .
