Question

Which of the following polynomials corresponds to the product of the multivariate polynomials 4x - 3y + 5 and x + 2y -3?

a. 5x - y + 2
b. 4x 2 - 6y 2 - 15
c. 4x 2 + 8xy - 12x - 3y + 5
d. 4x 2 - 6y 2 + 5xy - 7x + 19y - 15

Answer 1

Well, there had better be x^2, y^2, xy, x, y, and a constant term unless something odd occurs. It better end with -15.

Answer 3

the product is what you get when you multiply.
what will be the result of (4x -3y + 5)(x +2y -3)
