How to use it?
Factor polynomial
:
x^6-x^2*y^4
c^2-9
z^2-0.49
y*y/x-x^2+x*y/x-y^2
Least common denominator
:
z/(x+y)+x/(z+y)+y/(z+x)
x^(log(x)+1)*((log(x)+1)/x+log(x)/x)
((sqrt(a))/((sqrt(a))+(sqrt(b)))+(sqrt(b))/((sqrt(a))-(sqrt(b)))+(2*(sqrt(a*b)))/(a-b))
2/(a+2)+(a-2)/(a^2+4*a+4)/(a/(2*a-4)+(a^2+4)/(8-2*a)-2/(2*a+a^2))
Factor squared
:
-y^4+7*y^2+6
-y^4-y^2+2
-y^4+9*y^2-3
-y^2-2*y*b+b^2
How do you in partial fractions?
:
2*(-1+4*x^2/(1+x^2))/(1+x^2)^2
x^2/(x^2+1)^4
(1-x/(1+x))/(1+x)^3
((x-1)/(x+1))^2
