If `(a + bx)^-2 =1/4-3x+...,` then `(a, b) =`

If the binomial expansion of (a+bx)^(-2) is (1)/(4)-3x+......, then (a,b)=

If 1,2,3 and 4 are the roots of the equation x^4 + ax^3 + bx^2 +cx +d=0 then a+ 2b +c=

If 1,2,3 and 4 are the roots of the equation x^4 + ax^3 + bx^2 +cx +d=0 then a+ 2b +c=

If ((1-3x)^(1//2)+(1-x)^(5//3))/(sqrt(4-x)) is approximately equal to a+bx for small values of x , then (a,b)=

If (x+1) and (x-1) are factor of ax^(3) + bx^(2) + 3x+5 . Find the value of a and b

If (x+2) and (x-2) are factors of ax^4 + 2x - 3x^2 + bx - 4 , then the value of a + b is
