+33661 Without knowing the value of c the most general approach is to use the quadratic formula.
First rewrite as x2 + 11x + 12-9c = 0 and then solve as:
x = ( -11 ± √[121 - 4(12-9c)] )/2 or x = ( -11 ± √[73 + 36c] )/2
Once you have a value for c you can plug it in the expression above to get numerical values for x. Note that if c is a number less than -73/36 the resulting values of x will be complex.
