1. soru:

(x^2-3x+a)(x^2+7x+d)=(x^2+2x+b)(x^2+2x+c)
....(a+d-21)x^2.... = .... (b+c+4)x^2.....
Polinom eşitliğinden
a+d+21=b+c+4
a+d-(b+c)=25

2. soru
soruya özel bir çözüm
(2^6)^2 +2*2^6*2^3+(2^3)^2=(2^6+2^3)^2
m=64+8=72

3. soru
payda eşitlersek
[(x^3+2)(y-1) + ( y^3+2)(x-1)] /(xy-x-y+1)
[x^3y+y^3x-x^3-y^3+2x+2y -4]/(2-4+1)
- [xy(x^2+y^2)-(x+y)(x^2-xy+y^2)+2(x+y)-4]
gerisi malum
