64*y^3+x^3/125
64+y^3
64+x^3*y^3
64*x^2-9*y^2
Least common denominator
:
cos(x)/(1+sin(x))-sin(x)/(1-sin(x))
cos(x)/(1+sin(x))+sin(x)/(1-sin(x))
asin(x)^2*(10-2*x)/(5-x)^4+2*asin(x)/(sqrt(1-x^2)*(5-x)^2)
sqrt((x^2+1)/(x^2-1))*(x^2-1)*(x/(x^2-1)-x*(x^2+1)/(x^2-1)^2)/(x^2+1)
Factor squared
:
8*y^2+9*y+4
8*y^2-7*y*x-7*x^2
8*y^2-7*y*x-2*x^2
