How do you in partial fractions?:
2*a*(3*a-p)/(2*p-6*a)
2*x/(x^2+1)-2*x*(x^2-1)/(x^2+1)^2
(((y-y)/(3*y-3))+(1/(y-1)))/((y+1)/3)+(2/(y^2-1))
(x^2-12)/(x-3)-x/(3-x)
Factor polynomial:
x^3-1
x^7+1
c^5+1
x^2-4
Least common denominator:
(z/b-b/z)*6*z*b/(z+b)
(((z)/(b))-((b)/(z)))*((4*z*b)/(z+b))
(z/8+z/3)/z^2
(z-6*z/z+3)/z-3/z+3
Factor squared:
y^4+y^2-1
