1/9*y^2 - 1/6*y*x^2 + 1/16*x^4
the answer the book gives is
(1/3*y - 1/4*x^2)^2
is there anything special i need to do to factor this equation.
The calculator gives me this as the answer
(3*x^2 - 8)^2 / 144
I know if i factor it by hand i can get the proper answer but i have alot of these to do and im not sure what im doing wrong. Ive also tried this in the sage math application and it didnt show the proper form either.
Any help would be appreciated thanks.
