See the entire solution process below:

First, remove all of the terms from parenthesis. Be careful to handle the signs of each individual term correctly:

$3x^2 + 4x - 10 - 2x - 7 + 4x^2$

Next, group like terms:

$3x^2 + 4x^2 + 4x - 2x - 10 - 7$

Now, combine like terms:

$(3 + 4)x^2 + (4 - 2)x - 17$

$7x^2 + 2x - 17$

What is the standard form of a polynomial (3x^2+4x-10)-(2x+7-4x^2)(3x^2+4x-10)-(2x+7-4x^2)?
