(B) Given the expression: $\frac{3x^2 + 5}{(x^2 + 1)^2} = \frac{a}{x^2 + 1} + \frac{b}{(x^2 + 1)^2}$ Multiply both sides by $(x^2 + 1)^2$: $3x^2 + 5 = a(x^2 + 1) + b$ $3x^2 + 5 = ax^2 + a + b$ Comparing the coefficients of $x^2$ and the constant terms on both sides: For $x^2$: $a = 3$ For the constant term: $a + b = 5$ Substitute $a = 3$ into the second equation: $3 + b = 5 \implies b = 2$ Therefore,$(a, b) = (3, 2)$.

If $\frac{3x^2 + 5}{(x^2 + 1)^2} = \frac{a}{x^2 + 1} + \frac{b}{(x^2 + 1)^2}$,then $(a, b) = $
