Simplify this expression: $25x^2 + 30x^3 - 35x^6$ [closed]
$begingroup$
I was thinking about simplifying this expression:
$$25x^2 + 30x^3 - 35x^6$$
Note that I don't mean just factoring $5x^2$ from it!

"Simplifying" is vague and subjective (although not completely arbitrary; $2$ is clearly simpler than $frac{105+95}{2cdot 50}$). Do you mean "factor"?

Your expression factors as $frac{-5}{7}x^2a(x)b(x)c(x)$, where $a(x)$, $b(x)$, and $c(x)$ are, respectively,
$$left(!!x! -!! sqrt{!sqrt[3]{left(81!+!sqrt{48561}right)^2}! -! 10sqrt[3]{42}}!+!frac{!!!!!sqrt{!10sqrt[3]{!42}! -!! sqrt[3]{!left(81!+!sqrt{48561}right)^2}!+!!18sqrt{!!frac{2left(81+sqrt{48561}right)}{!sqrt[3]{!left(81+sqrt{48561}right)^2}! - 10sqrt[3]{42}}}}}{sqrt[6]{2^5}sqrt[3]{21}sqrt[6]{81+sqrt{48561}}}!!right)$$
