(a+b)^2-2ab
(9)^2-2(10)
81-20
61
So a^2+b^2 will be 61

[+] them
Aree,what u are trying to say....write in hindi
agar a+b =9 and a multiply by b gives 10 so what is a[square] and b[square]not add them
Par question mai a(square)+b(square) pucha hai
thats true but in paper they ask for a and b square ant add them
sorry not add them
okk then from ab=10,a=10/b,put this in equation a+b=9,now u will get the value of b,then put value of b in 10/b,u will get the value of a
thanks
