The value of `(4m^2-a^2 + 2ab-b^2)/(2m+ a- b)`​

If a+b=10 and ab=16 find the value of a^(2)-ab+b^(2) and a^(2)+ab+b^(2)

If a+b=10 and ab-=16, find the value of a^(2)-ab+b^(2) and a^(2)+ab+b^(2)

Find the value of ( m^4 - m^2n^2) ÷ m^2 is

If a^(2) +b^(2) = x, ab = y then the value of (a^(4) +b^(4))/(a^(2) -ab sqrt(2) +b^(2)) is

If a:b=2:3, then the value of (5a^(3)-2a^(2)b):(3ab^(2)-b^(3)) is :

If (x+1)/(x-1)=(a)/(b) and (1-y)/(1+y)=(b)/(a), then the value of (x-y)/(1+xy) is (2ab)/(a^(2)-b^(2)) (b) (a^(2)-b^(2))/(2ab) (c) (a^(2)+b^(2))/(2ab) (d) (a^(2)-b^(2)backslash)/(ab)
