Math 10 Week 5 – Distributing Method for Trinomials

This week we learned different methods you can use to to multiply to monomials to create a trinomial. In this blog post I am going to show you how to use the the distributive method because I find it the easiest and most efficient way to find your answer.

Let’s say you have an equation that looks like this:

(7x+9)(5x+2)

This is where you can use this method. All you have to do is multiply the different terms in a specific pattern.

 

This photo shows which terms need to be multiplied together, in what order (Blue 1st, red 2nd, green 3rd and black 4th).

If done correctly, your answer should look like this:

35x^{2} + 14x + 45x + 18

Then you add your like terms together:

35x^{2} + 59x + 18
