- Factor polynomial:
- y^2-4*y+4
- x*y^3+x*y^2*b
- x-y^2+1-3*y^2
- x+x^7/7
- Least common denominator:
- (u^2-2*u+4)/(4*u^2-1)*(2*u^2+4)/(u^3+8)
- tan(x^2)/(x*log(2))-x/(sqrt(x^2)*sqrt(1-x^2))+2*x*(1+tan(x^2)^2)*log(x)/log(2)
- tan(x)^(2*(1-x)^(2/3))*(-4*log(tan(x))/(3*(1-x)^(1/3))+2*(1-x)^(2/3)*(1+tan(x)^2)/tan(x))
- tan(x)^(1/x)*(-log(tan(x))/x^2+(1+tan(x)^2)/(x*tan(x)))
- Factor squared:
