    Exclamation [SOLVED] As Maths!

    please help

    (x) = 4x2 + 12x + C

    where C is a constant,

    given that f(x) = 0 has equal roots, find the value of C and hence solve f(x) = 0

    i've already found that C=9

    thanks in advance

    \begin{gathered}<br />
  f(x) = \left( {2x + 3} \right)^2  = 0 \hfill \\<br />
   \leftrightarrow x =  - \frac{3}<br />
{2} \hfill \\ <br />
