multiplying trinomials

In this blog let us learn about multiplying trinomials,we can again understand this with the help of an example problem,but this example problem is comparatively a small one because this is done through the vertical method,in the past we have also seen about multiplication rule.

Multiply (x² + 2x + 4) and (x² + 6x + 5)

Solution:
(x² + 2x + 4) ----- First Trinomial
(x² + 6x + 5) ----- Second Trinomial
Let us follow vertical method of multiplication.
multiplication of trinomial
Hence, the product of (x² + 2x + 4) and (x² + 6x + 5) is x4 + 8x3 + 21x² + 34x + 20.In the next blog we will learn about percentage change calculator,hope you like the above example of multiplying trinomials,please leave your comments if you have any doubts.
