How to use it?
Least common denominator:
(z-3)/(z+3)*(z+(z^2)/(3-z))
(z/3)+(54-z-z/3)+z
-z/1-z/2
y/(x-y)+x/(y-x)
Factor polynomial:
m^2+m-2
z^3+z^2+z+1
z^3-z^2-9*z+9
z^3-z^2-5*z+125
Factor squared:
y^4+y^2-10
y^4+8*y^2-1
-y^4-4*y^2+4
y^4-4*y^2-4
How do you in partial fractions?:
(x^2-3*x+2)/(x-2)
-1+x/(x^2-2*x+2)+(x^2+3*x+2)/(x^2-x+2)
(10*x^3-15*a*x^2)/(21*a*x^3-14*x^4)
45*x*y^2/(75*y^2)
Identical expressions
(z/ three)+(fifty-four -z-z/ three)+z
(z divide by 3) plus (54 minus z minus z divide by 3) plus z
(z divide by three) plus (fifty minus four minus z minus z divide by three) plus z
z/3+54-z-z/3+z
(z divide by 3)+(54-z-z divide by 3)+z
Similar expressions
(z/3)-(54-z-z/3)+z
(z/3)+(54-z-z/3)-z
(z/3)+(54+z-z/3)+z
(z/3)+(54-z+z/3)+z
