# Multiply the binomials:

x−2y and 2x−y

Answer :

Consider two binomials as x−2y and 2x−y

Now,to get the product of two binomials x−2y and 2x−y we use the

**distributive law** i.e. (x−2y)×( 2x−y) = x(2x)-x(y)-2y(2x)-2y(-y) = 2x^{2}-xy-4xy + 4y^{2}

Therefore ,the product of x−2y and 2x−y is 2x^{2} + 4y^{2}-5xy.
