Question

It’s polynomial operations I need the answer and all the work written out.

Answer 1

`x^2+14x^3y^2-6x`

Step-by-step explanation:

Given the below polynomials expression;

`(4x^2+7x^3y^2)-(-6x^2-7x^3y^2-4x)-(10x+9x^2)`

The 1st step to solving the above is to clear the brackets while minding the signs as shown below;

`4x^2+7x^3y^2+6x^2+7x^3y^2+4x-10x-9x^2`

The 2nd step is to group like terms;

`4x^2+6x^2-9x^2+7x^3y^2+7x^3y^2+4x-10x`

Let's go ahead and evaluate;

`x^2+14x^3y^2-6x`
