Answer:
(-7, -3)
Step-by-step explanation:
So the formula is (x, y) --> (-y, x) for a 90 degrees counterclockwise rotation.
To apply this formula to (-3,7), first identify which is the x-coordinate and which is the y-coordinate.
x-coordinate is -3 & y-coordinate is 7
Then you literally just substitute it into the formula like so:
(-y, x) -->(-(7), (-3)) --> (-7, -3)
Try to put parantheses around the coordinate when substituting to prevent confusion & incorrect negative signs.

Answer:
3x²-3x+2
Step-by-step explanation:
To find A-B:
Substitute A and B with given values:
x²-(-2x²+3x-2)
Epand the bracket since there is a -1 in front of the bracket (the 1 is invisible)
x²+2x²-3x+2
Simplify:
3x²-3x+2
