Answer 1

$(4x^2+8x-2)-(2x^2-4x+3)\\\\=4x^2+8x-2-2x^2+4x-3\\\\=(4x^2-2x^2)+(8x+4x)+(-2-3)\\\\=\boxed{2x^2+12x-5}$

Answer 2

Answer:

$2x^2+12x-5$

Step-by-step explanation:

The given equation is:

$(4x^2+8x-2)-(2x^2-4x+3)$

Upon solving the above equation, we get

$4x^2+8x-2-2x^2+4x-3)$

Now, rewriting the above expression by combining the like terms, we get

$4x^2-2x^2+8x+4x-2-3$

Now, solving the like terms together, we get

$2x^2+12x-5$

which is the required standard form of the given expression.
