#### Topic: Large equations

I wrote a program several months ago, that determines the factors of an equation.

It does it's job and I use "Graph" to confirm my results.

But I have a 'large' equation that my program don't agree!

The equation is :

48x^22 + 32x^20 + 81.12x^18 - 252.64x^14 - 149.1428x^13 + 125.76x^12 - 99.4285x^11 - 56.6228x^9 + 442.12x^5 + 114x^4 - 220.08x^3 + 76x^2 - 149.34

I get :

* No Rational roots found *

4 irrational root(s)

between

-0.9266986843 and -0.9266986842 y

0.9266978347 and 0.9266978348

0.9591199950 and 0.9591199951

1.0641530325 and 1.0641530326

Sorry, but I'm partially blind and am having difficulty reading the graph.

Do you agree with my results ?

Can you help please ?
