Question

Factor 2a5b + 2a4b2 + 2a3b3.
2a2b(a2 + ab2+ ab)
2a3b(a2 + ab + b2)
2ab3(a3 + ab + b2)

Answer 1

Factor 2a5b + 2a4b2 + 2a3b3 means \(2a^5b + 2a^4b^2 + 2a^3b^3\), I think...
Factoring is all about looking for common factors.
HEre, you've got three terms:
\(2a^5b\)
\(2a^4b^2\)
\(2a^3b^3\)

What is common in these terms? I see a 2, I see \(a^3\), and then there is another one.

Put all of the common factors outside brackets, and what is left inside:

\(2a^3...\cdot(...+...+...)\)

Well, with these multiple choice questions, you don't even have to do it! Your options are limited...
