See a solution process below:

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

$x^2 - 3x + 5 + x^2 + 2x - 3$

Next, group like terms:

$x^2 + x^2 - 3x + 2x + 5 - 3$

Now, combine like terms:

$1x^2 + 1x^2 - 3x + 2x + 5 - 3$

$(1 + 1)x^2 + (-3 + 2)x + (5 - 3)$

$2x^2 + (-1)x + 2$

$2x^2 - 1x + 2$

$2x^2 - x + 2$

What is the standard form of a polynomial (x^2-3x+5)+(x^2+2x-3)(x^2-3x+5)+(x^2+2x-3)?
