You can put this solution on YOUR website! simplify the fraction:
3x^3-30x^2+75x / 25x^2-x^4
-------------
Factor where you can:
---
[3x(x^2 - 10x + 25)]/[x^2(25-x^2)]
---
= [3x(x-5)^2] / [x^2(5+x)(5-x)]
---
= [3x(x-5)^2] / [-x^2(x+5)(x-5)]
---
Cancel factors common to numerator and denominator:
---
= [3(x-5)] / [-x(x+5)]
