We have to simplify the expression:


\begin{gathered} -15y^2+3\mleft[-y^2-2\mleft(5-y^2\mright)\mright]​ \\ -15y^2+3\lbrack-y^2-10+2y^2\rbrack \\ -15y^2+3\lbrack y^2-10^{}\rbrack \\ -15y^2+3y^2-30 \\ -12y^2-30 \\ -6(2y^2-5) \end{gathered}

Answer:

We can express the simplified expression as -12y^2-30 or factorized as -6(2y^2-5).
