a^(2)+b-ab-a=?

a o+ b=(a+b)^(2)-ab a**b=(ab)^(2)-ab a"@"b=(a-b)^(2)-ab Find the value of (((1o+2)**3)"@" 20) :

a o+ b=(a+b)^(2)-ab a**b=(ab)^(2)-ab a"@"b=(a-b)^(2)-ab Find the value of (5o+6)-(6"@"3)+(2**4)

If [ sqrt (a ^(2) + b^(2) + ab)] + [ sqrt (a^(2) + b^(2) - ab)] = 1 then what is the value of (1 - a^(2)) (1 - b^(2)) ?

Factorise the using the identity a ^(2) - 2 ab + b ^(2) = (a -b) ^(2). 4a ^(2) - 4 ab + b ^(2)

( a - b) ^(2) + 2ab = ? A. a^(2) - b^(2) B. a^(2) + b^(2) C. a^(2) - 4ab + b^(2) D. a^(2) - 2ab + b^(2)

If a and b are non zero rational unequal numbers, then ((a+b)^(2)-(a-b)^(2))/(a^(2)b-ab^(2)) is equal to :

Simplify the following: 6a-2b-ab-(3a+b-ab)+2ab-b+a

= (b + a) n ^ (2) + (2ab + b ^ (2) + a ^ (2)) n + a ^ (2) b + ab ^ (2)
