Question

help please!!

Answer 1

\[(3x+1)\times 2x-x^2\times 3\]

\[=6x^2+2x-3x^2\]
\[=3x^2+2x\] that is the best you can do

Answer 2

well, you could write \(x(3x+2)\) if you like for the numerator
nothing cancels, that is it

Answer 3

final answer would be
\[\frac{x(3x+2)}{(3x+1)^2}\]

Answer 4
