You can put this solution on YOUR website!
xx = x + 72
\n" ); document.write( "xx - x - 72 = 0
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=1, b=-1 and c=-72
\n" ); document.write( "---
\n" ); document.write( "to solve the quadratic equation, by using the quadratic formula, copy and paste this:
\n" ); document.write( "1 -1 -72
\n" ); document.write( "into this solver: https://sooeet.com/math/quadratic-equation-solver.php
\n" ); document.write( "---
\n" ); document.write( "the quadratic has two real roots at:
\n" ); document.write( "---
\n" ); document.write( "x = 9
\n" ); document.write( "x = -8
\n" ); document.write( "---
\n" ); document.write( "either root works fine for this problem:
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "x = 9
\n" ); document.write( "OR
\n" ); document.write( "x = -8
