`1 - (a^(2) + b^(2)) + 2ab`

1-2ab - (a ^(2) +b ^(2)) = ?

The value of the determinant |{:(1+ a^(2) - b^(2),2 ab , - 2b),(2ab, 1 - a^(2) + b^(2), 2a),(2b , -2a , 1-a^(2) - b^(2)):}| is equal to

If a = 2 and b = -1 , then a^(2) + b^(2) + 2ab = "________"

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 : 1 + 2 ab - (a ^(2) + b ^(2))

What is the lowest common multiple of ab (x^(2)+1) + x (a^(2)+b^(2)) and ab (x^(2)-1) + x(a^(2)-b^(2)) ?

(ab) +2 (a + b) +1
