Question

°24 БАЛЛА!!
Выполните преобразование по соответствующей формуле:
(9+a)^2 (a+c)^2
(8-b)^2 (11-y)^2
(3y-4)^2 (10+4c)^2
(5a+6b)^2 (-3c+a)^2
(a-y^3)^2 (a^+b^2)^2

Answer 1

(9+a)^2=81+18a+a^2;
(a+c)^2=a^2+2ac+b^2;
(8-b)^2=64-16b+b^2;
(11-y)^2=121-22y+y^2;
(3y-4)^2=9y^2-24y+16;
(10+4c)^2=100+80c+16c^2;
(5a+6b)^2=25a^2+60ab+36b^2;
(-3c+a)^2=a^2-6ac+9c^2;
(a-y^3)^2=a^2-2ay^3+y^6;
(a^2+b^2)^2=a^4+2 (ab)^2+b^4
