Week 8- Math 10 Polynomials

This week in math 10 how to factor and expand fractional polynomials. These questions seemed difficult at first but once I used methods we’ve learned before, I got the hang of it.

To do this, I followed three simple steps:

  1. Recognize polynomials.
  2. Identify binomials and trinomials.
  3. Find the product of a monomial and binomial.

A question that I struggled to complete was

4x^2/ 4 – 80xy/4+144^2/4

To complete this I had to find the GCF (4)

Now I could factor this polynomial: 4(x^2- 20xy +36y^2)

x^2-20x+36

= 4 (x-18y) (x-2y)
