- The binomial expansion, in ascending powers of \(x\), of
$$( 3 + p x ) ^ { 5 }$$
where \(p\) is a constant, can be written in the form
$$A + B x + C x ^ { 2 } + D x ^ { 3 } \ldots$$
where \(A\), \(B\), \(C\) and \(D\) are constants.
- Find the value of \(A\)
Given that
- \(B = 18 D\)
- \(p < 0\)
- find
- the value of \(p\)
- the value of \(C\)
