 Question 321341: Hi, I am having a problem with two variables on a dividend when dividing polynomials. My exact problem is: 2x^3-9x^2y-12^y+17xy^2 divided by 2x-3y I know the usual process and I have gotten to the second equation involving getting a difference of -6x^2y but now I am stuck, because when I divide -6x^2y to the first term of the divisor, I have to multiply that quotient (which is -3xy) to the brought-down -12y^3, and as far as I remember I can't multiply it because -12y^3 has no x variable.
