$\"5m%5E2%2B7=52\"$ If we subtract 7 from both sides of the equal sign, we get
\n" ); document.write( " $\"5m%5E2=52-7\"$
\n" ); document.write( " $\"5m%5E2=45\"$ Iwwe divide both sides of the equal sign by 5, we get
\n" ); document.write( " $\"m%5E2=45%2F5\"$
\n" ); document.write( " $\"m%5E2=9\"$
\n" ); document.write( "There are two numbers that, when squared, equal 9.
\n" ); document.write( "(We could say that we are \"taking square roots of both sides of the equal sign, but there is also the messy issue of those $\"%22%2B%22\"$ and $\"%22-%22\"$ signs).
\n" ); document.write( " $\"m%5E2=9\"$ ---> $\"system%28m=sqrt%289%29%2C%22or%22%2Cm=-sqrt%289%29%29\"$ ---> $\"highlight%28system%28m=3%2C%22or%22%2Cm=-3%29%29\"$ \n" ); document.write( "
