- (a) (i) Show that \(\frac { 1 } { 3 - 2 \sqrt { x } } + \frac { 1 } { 3 + 2 \sqrt { x } }\) can be written in the form \(\frac { a } { b + c x }\), where \(a , b\) and \(c\) are constants to be determined.
(ii) Hence solve the equation \(\frac { 1 } { 3 - 2 \sqrt { x } } + \frac { 1 } { 3 + 2 \sqrt { x } } = 2\).
(b) In this question you must show detailed reasoning.
Solve the equation \(2 ^ { 2 y } - 7 \times 2 ^ { y } - 8 = 0\).
