![(a.y^{3} +3y^{2} -3 ) = (ay^{2} +(4a+3)y +4(4a+3))(y-4) +64a+45](https://tex.z-dn.net/?f=%28a.y%5E%7B3%7D%20%2B3y%5E%7B2%7D%20-3%20%29%20%3D%20%28ay%5E%7B2%7D%20%2B%284a%2B3%29y%20%2B4%284a%2B3%29%29%28y-4%29%20%2B64a%2B45)
so A = 64a +45
(![2y^{3} -5y+a =(2y^{2} +8y +27)(y-4) +108 +a](https://tex.z-dn.net/?f=2y%5E%7B3%7D%20-5y%2Ba%20%3D%282y%5E%7B2%7D%20%2B8y%20%2B27%29%28y-4%29%20%2B108%20%2Ba)
so B = 108 +a
2A-B=0--> 2(64a+45)-108-a=0--> a =18/127
