ab(x^(2)+1)+4(a^(2)+b^(2))

Find the LCM of the polynomials ab(x^(2)+1)+x(a^(2)+b^(2)) and ab(x^(2)-1)+x(a^(2)-b^(2))

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)

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)) ?

factorize : ab(x^2+1)+x(a^2+b^2)

The area enclosed in the region (x^(2))/(a^(2))+(y^(2))/(b^(2)) =1 is (i) (pi ab)/(4)-(1)/(2)ab( ii (pi ab)/(4) (iii) piab (iv) none of these

Simplify.(4a-b)/(1-4ab)-(4a+b)/(1+4ab)-(4b(1-8a^(2)))/(16a^(2)b^(2)-1)

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

If a^(4) + a^(2) b^(2) +b^(4)=8, a^(2) + b^(2) + ab= 4 find ab
