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:
- Recognize polynomials.
- Identify binomials and trinomials.
- 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)
