    2 a ^(2) b ^(2) - 4a b ^(2) - 70 b ^(2)

    Show that (a - b)^(2), (a^(2) + b^(2)) " and " (a + b)^(2) are in AP.

    If ( a + b - 6)^(2) +a^(2) + b^(2) + 1 + 2b = 2ab + 2a, then value of a is

    Simplify : a^(2)b - a^(2)b^(3) +4a^(2)b^(3) - 2a^(3)b^(2) - a^(3)b + 2a^(3) b^(2)

    If 3a ^(2) = b ^(2) ne 0, then the value of ((a + b ) ^(2) - (a - b ) ^(3))/((a + b ) ^(2) + (a-b) ^(2)) is:
