Answer 2

The result of the subtraction will be $9+7x-5x^2$.

Given,

The expressions: $3x^2- 6x - 4$ and $5 + x - 2x^2$.

To Find,

The result when $3x^2- 6x - 4$ is subtracted from $5 + x - 2x^2$.

Solution,

The method of finding the result of the subtraction is as follows -

$3x^2- 6x - 4$ and $5 + x - 2x^2$ are two algebraic expressions. When one algebraic expression is subtracted from another, the coefficients of the respective powers get subtracted.

So the subtraction will be $5+x-2x^2 - (3x^2-6x-4)=5+x-2x^2 - 3x^2+6x+4$

$=9+7x-5x^2$

Hence, the result of the subtraction will be $9+7x-5x^2$.
