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]
