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

If a and b are the roots of x^2 - 2x - 1 = 0 , then value of a^2b + ab^2 is:

If (5x+6)/((2+x)(1-x))=a/(2+x)+b/(1-x) , then the values of a and b respectively are:

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 lim_(x to oo) [ (x^(3)+1)/(x^(2)+1)-(ax+b)]=2 , then the values of a and b are -

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

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

The solution of the equation |x-1|+2|x+1|+|x-2|<=8 is x in[a,b], then the value of |b-a|+(1)/(|b+a|) is :

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

If quad 1(1)/(1-2x+x^(2))=1+b_(1)x+b_(2)x^(2)+b_(3)x^(3)+...oo,|x|<1, then the value of b_(1) is
