SOLUTION: Please help me solve this problem.
{{{3x^3y^4+192x^3}}}
I came up with {{{3x^3(y^4+64)}}} as an answer. Can someone tell me if this is correct?
You can put this solution on YOUR website! There is no problem per se. You presented an expression.
From your attempted answer, I suspect that you want to factor it.
3x^3* (y^4+64) can be factored again
3x^3* (8-4y+y^2)*(8+4y+y^2)
