You can't really factor this polynomial neatly because it has one real root (between 2 and 3) and three imaginary roots.

(x + 3)(4x + 5)

(4x + 16)(x + 3)

sqrt(4)=2 sqrt(169)=13 (2x+13)(2x-13)

Yes, if there is no remainder after division, the divisor is a factor.

It is: 2x(2x+11)

If that's + 4x2, the answer is 2x(x2 + 2x - 4)

4X2+X3+3X+7Y+2X3 can only be simplified to 3X3+4X2+3X+7Y, because X3 and 2X3 are the only like terms.
