Find the value of the polynomial:

7x^2y−2xy^2−6x^2y+3xy^2−xy+8 for x=−2, y=4
Answered by oobleck
just plug in the numbers.
7(-2)^2*4−2(-2)*4^2−6(-2)^2*4+3(-2)*4^2−(-2)*4+8
Do it by hand, or plug it into any online calculator.

Or, simplify a bit first, and evaluate
x^2y + xy^2 - xy + 8 = xy(x+y-1) + 8
that might be a bit easier.
