Answer:

$2x^2+xy-3y^2$

Step-by-step explanation:

Start by taking everything out of the parentheses:

$3x^2-2xy-2y^2-x^2-(-3xy)-(y^2)$

Note two negatives make a positive:

$3x^2-2xy-2y^2-x^2+3xy-y^2$

Combine like terms:

$3x^2-x^2-2xy+3xy-2y^2-y^2$

Simplify

$2x^2+xy-3y^2$

First you have to figure out the total.
42+35+23= 100
So plug it in.
23/100
23%
Your answer is 23%.
Hope this helped ^-^
