Simplify:

(1)


4w^2+7w^2+7z^2

(2)


15w-6w+14w^2

Step-by-step explanation:

(1)

take common


w^2
\begin{gathered} 4w^2+7w^2+7z^2 \\ =w^2(4+7)+7z^2 \\ =11w^2+7z^2 \end{gathered}

(2)

take


w

common from the given equation


\begin{gathered} 15w-6w+14w^2 \\ =w(15-6)+14w^2 \\ =9w+14w^2 \end{gathered}

Final answer:


\begin{gathered} 4w^2+7w^2+7z^2=11w^2+7z^2 \\ 15w-6w+14w^2=9w+14w^2 \end{gathered}
