The given expression for b can be simplified:
\(b = c + d^2/c\)
or,\(b = \frac{c}{c} + \frac{d^2}{c}\)
or, \(b = 1 + \frac{1}{a}\) (from the eqn for a we can find \(\frac{d^2}{c}\) as a reverse for a)
option A
\(b = c + d^2/c\)
or,\(b = \frac{c}{c} + \frac{d^2}{c}\)
or, \(b = 1 + \frac{1}{a}\) (from the eqn for a we can find \(\frac{d^2}{c}\) as a reverse for a)
option A
