We start with the formula, $\"Ap=base%2Aheight\"$ -----> basic eqn.
\n" ); document.write( " $\"100squnits=x%2A%28x%2B15%29\"$
\n" ); document.write( " $\"100=x%5E2%2B15x\"$
\n" ); document.write( " $\"x%5E2%2B15x-100=0\"$
\n" ); document.write( " $\"%28x%2B20%29%28x-5%29=0\"$
\n" ); document.write( "2 values:
\n" ); document.write( " $\"x=-20\"$ ----------> don't use, \"negative\"
\n" ); document.write( " $\"x=5\"$ ------------> the one to used = height
\n" ); document.write( " $\"x%2B15=5%2B15=20\"$ ---> = base
\n" ); document.write( "Go back basic eqn to check,
\n" ); document.write( " $\"100=5%2A20\"$
\n" ); document.write( " $\"100square+units=100+square+units\"$
