Question

Factor the following expression.
198q3r2 – 184q2r2 + 18qr2

Answer 1

notice all parts have r^2 and at least one q. so both can be factored out of the bat. this becomes:
\[r^2q(198q^2-184q+18)\]

Answer 2

this can be factored further.

Answer 3

all can also factor out a two
\[2r^2q(99q^2-92q+9)\]

Answer 4

You can also factor:

\[2r^{2}q(99q^{2} - 92q + 9)\]\[2r^{2}q(9q -1)(11q - 9)\]

Answer 5

awh you beat me to it. but yeah basically that's it.
