Simplify: 4y(3y + 4)

Here we have 4y and 3y + 4.

Now the product of these terms is as follows:


The procedure involved in the multiplication is :


Step1.Write the product of the expressions using multiplication symbol: 4y(3y + 4).


Step2.Use distributive law :Multiply the monomial by the first term of the binomial then multiply the monomial by the second term of the binomial and then add their products: 4y(3y) + 4y(4)


Step3.Simplify the terms: 12y2 + 16y


Hence 4y(3y + 4) = 12y2 + 16y
