જો $\frac{ax - 1}{(1 - x + x^2)(2 + x)} = \frac{x}{1 - x + x^2} - \frac{1}{2 + x}$ હોય,તો $a = $

$\begin{aligned} & \text{જો } \frac{4x^2+5x^4+7}{(x^2+1)(x^4+x^2+1)} = \frac{Ax+B}{x^2+1} \\ & + \frac{Cx^3+Dx^2+Ex+F}{x^4+x^2+1}, \text{ હોય તો } \\ & B+2(D+F+E)-C \cdot A = \end{aligned}$

જો $\frac{x^2-3x+1}{(x-1)(x-2)(x-3)}=\frac{A}{x-3}+\frac{B}{(x-1)(x-2)}+\frac{C}{(x-1)(x-2)(x-3)}$ હોય,તો $B=$

જો $\frac{x^2+3}{(x^2+1)(x^2+2)}=\frac{Ax+B}{x^2+1}+\frac{Cx+D}{x^2+2}$ હોય, તો $A+B+C+D=$

જો $\frac{x^4-6 x^3+9 x^2+5 x-20}{x^2-x-2}=f(x)+\frac{a}{x+p}+\frac{b}{x+q}$ હોય,તો $2(a+b)=$

$\frac{3 x^{2}+1}{x^{2}-6 x+8}$ ની કિંમત શું થાય?
