Factor 3x2y2 - 2xy2 - 8y2?

Answer 1

\(\normalsize\color{darkgreen}{ \rm 3x^2y^2 - 2xy^2 - 8y^2 }\) factor out of \(\normalsize\color{darkgreen}{ \rm y^2 }\)

Answer 2

\[3x^2y^2 - 2xy^2 - 8y^2\]
Search for common terms.
Group them together.
\[y^2[3x^2 - 2x - 8]\]
Now solve for the quadratic equation inside the parenthesis and you'd have your factorized form.
