Express the answer in standard form.

Answer:

$-2x^{2} +8x-10$

Step-by-step explanation:

Standard form is basically where the degrees of the terms are in descending order.

First, let's distribute the negative sign to the terms in the second parentheses:

$-(3x^{2} -5x+3) = -3x^{2} +5x-3$

Now, we can just combine like terms with the terms from the first parentheses:

$x^{2} +3x - 7 - 3x^{2} +5x-3 = -2x^{2} +8x-10$

So, our answer is: $-2x^{2} +8x-10$
