Question

2х в квадрате + х -3х в кубе

Answer 1

$2x^{2}+x-3x^{3}=x(2x+1-3x^{2})=x(-3x^{2}+2x+1)=x(-3x^{2}+3x-x+1)=x(-3x(x-1)-(x-1))=x(-(x-1)-(x-1))=x(-3x(x-1)-(x-1))=x(-(x-1))(3x+1)=-x(x-1)(3x+1)$

Answer 2

To simplify the expression, let's combine like terms and write it in a more organized form:

2x^2 + x - 3x^3

The expression has a quadratic term (2x^2), a linear term (x), and a cubic term (-3x^3). To further simplify, we arrange the terms in descending order of exponents:

-3x^3 + 2x^2 + x

And that's the simplified form of the given expression.
