Multiply (2x+3y)(x-y)

The given polynomials are 2x−3y and x−y.

We multiply them as follows:

(2x−3y)(x−y)

=(2x×x)+(2x×−y)+(−3y×x)+(−3y×−y)

=2x 2 −2xy−3xy+3y 2

=2x 2 −5xy+3y 2

Hence, (2x−3)(x−y)=2x

2 −5xy+3y 2 .

2x^2 +xy - 3y^2

Step-by-step explanation:

2x(x-y) +3y(x-y)

2x^2+xy - 3y^2

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2
