Web24 nov. 2012 · You can choose x=15a/c and y=5b/c as new variables. The new equation is x 2 +y 2 +9-xy-3y-3x=0 or x 2 -x (y+3)+y 2 -3y+9=0 It is a quadratic equation in x. The discriminant is D= (y+3) 2 -4 (y 2 -3y+9)=-3 (y 2 -6y+9), negative or zero. To get a solution, D must be zero, so y=3. That involves x= 3. ehild Nov 23, 2012 #8 haruspex Science … Web16 mei 2024 · Question 5.
