L = 5w + 7
\n" ); document.write( "Lw = 108
\n" ); document.write( "---
\n" ); document.write( "Lw = 108
\n" ); document.write( "(5w + 7)w = 108
\n" ); document.write( "5ww + 7w - 108 = 0
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=5, b=7, and c=-108
\n" ); document.write( "---
\n" ); document.write( "to solve the quadratic equation, by using the quadratic formula, plug this:
\n" ); document.write( "5 7 -108
\n" ); document.write( "into this: https://sooeet.com/math/quadratic-equation-solver.php

\n" ); document.write( "the two real roots (i.e. the two x-intercepts), of the quadratic are:
\n" ); document.write( "w = 4
\n" ); document.write( "w = -5.4
\n" ); document.write( "---
