Answer:

[tex]x^2+14x^3y^2-6x[/tex]

Explanation:

Given the below polynomials expression;

[tex](4x^2+7x^3y^2)-(-6x^2-7x^3y^2-4x)-(10x+9x^2)[/tex]

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

[tex]4x^2+7x^3y^2+6x^2+7x^3y^2+4x-10x-9x^2[/tex]

The 2nd step is to group like terms;

[tex]4x^2+6x^2-9x^2+7x^3y^2+7x^3y^2+4x-10x[/tex]

Let's go ahead and evaluate;

[tex]x^2+14x^3y^2-6x[/tex]
