find the intergral solutions(x,y) of the equation 2xy – 4x2 + 12x – 5y = 11
find the intergral solutions(x,y) of the equation
2xy – 4x2 + 12x – 5y = 11
1 Answer
vsujji
4x^2-12x+11=2xy-5y
[2x]^2-2[2x]3+9-9+11=2xy-5y
[2x-3]^2+2=2xy-5y
[2x-3]^2+2=y[2x-5]
so by trial and error method we get [x,y]=[3,11] ;[4,9]
