: Let's say that a company's profitability, p(t), follows p(t)= t^2 - 5t - 50 with
\n" ); document.write( "p(t) in units of $1K and t = fiscal months. How long in years will it take the company to be $100K in the black (i.e., p(t)=$100,000)?
\n" ); document.write( ":
\n" ); document.write( "The equation for this problem, solve for t:
\n" ); document.write( "t^2 - 5t - 50 = 100
\n" ); document.write( ":
\n" ); document.write( "t^2 - 5t - 50 - 100 = 0
\n" ); document.write( ":
\n" ); document.write( "t^2 - 5t - 150 = 0
\n" ); document.write( ":
\n" ); document.write( "Factor this to:
\n" ); document.write( "(t-15)(t+10) = 0
\n" ); document.write( ":
\n" ); document.write( "The positive solution:
\n" ); document.write( "t = 15 yrs to be 100 k in the black \n" ); document.write( "

\n" );
