If `(1 -2x)/(3 + 2x - x^(2)) = (A)/(3 -x ) + (B)/(x + 1)` ,then the value of A + B is

If (x^(3))/((2x-1) (x+2) (x-3))=A+ (B)/(2x-1) +(C )/(x+2) + (D)/(x-3), then the value of A is-

If a=x+(1)/(x),b=x-(1)/(x), then the value of a^(2)+2ab-3b^(2) is

The HCF of the polynomials (2x - 1) (5x^(2) -ax + 3) and (x -3) (2x^(2) + x +b) " is " (2x -1) (x -3) Then the values of a and b respectively are _____

If A=(1+2x)/(1-2x) and B=(1-2x)/(1+2x) , then the value of (A+B)/(A-B) is: यदि A=(1+2x)/(1-2x) और B=(1-2x)/(1+2x) , (A+B)/(A-B) का मान ज्ञात करें

(3x-2)/((x +1) ^(2) (x +2))=(A)/(x+1) + (B)/((x +1)^(2))+ (C )/(x +3), then A + B+C =
