i want to know how to solve this thing ;D
Two ways you can solve it
1) By using formula
(a+b+c)² = a² + b² +c² +2ab+2bc+2ac
2) By Foiling
(a+b+c)² = (a+b+c)((a+b+c)
Method 2
(11-xy-y)² = (11-xy-y)(11-xy-y)
= 121-11xy-11y-11xy + x²y² +xy²-11y+xy² +y²
=121 -22xy -22y+ x²y²+y² +2xy²
Method 1
(11-xy-y)² = 11² +y²+x²y² -2(11)xy -2(11)y² +2xy²
= 121+y²+x²y²-22xy-22y+2xy²
(11 - xy - y)^2 = (11 - xy - y)(11 - xy - y) = 121 + (xy)^2 + y^2 - 22y - 22xy + 2x(y^2)
