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

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

Graph each equation

aliya0001 [1]

Just go one point at a time on your graph:
What does y equal when x is zero?
When x is 1?
When x is 2?
That's how you plot a graph.
