Solve $\"%283x%2B3%29%5E2=16\"$
\n" ); document.write( "Use the square root property:
\n" ); document.write( "For any real number c, if $\"x%5E2=c\"$ , then $\"x=sqrt%28c%29\"$ or $\"x=-sqrt%28c%29\"$ .
\n" ); document.write( " $\"%283x%2B3%29%5E2=16\"$
\n" ); document.write( " $\"sqrt%28%283x%2B3%29%5E2%29=%2B-sqrt%2816%29\"$
\n" ); document.write( " $\"3x%2B3=4\"$ or $\"3x%2B3=-4\"$
\n" ); document.write( " $\"3x%2B3-3=4-3\"$ or $\"3x%2B3-3=-4-3\"$
\n" ); document.write( " $\"3x=1\"$ or $\"3x=-7\"$
\n" ); document.write( " $\"3x%2F3=1%2F3\"$ or $\"3x%2F3=-7%2F3\"$
\n" ); document.write( " $\"highlight%28x=1%2F3%29\"$ or $\"highlight%28x=-7%2F3%29\"$
\n" ); document.write( ":
\n" ); document.write( "Check:
\n" ); document.write( "if x=1/3
\n" ); document.write( " $\"%283%281%2F3%29%2B3%29%5E2=16\"$
\n" ); document.write( " $\"%281%2B3%29%5E2=16\"$
\n" ); document.write( " $\"4%5E2=16\"$
\n" ); document.write( " $\"16=16\"$ x=1/3 checks out.
\n" ); document.write( "if x=-7/3
\n" ); document.write( " $\"%283%28-7%2F3%29%2B3%29%5E2=16\"$
\n" ); document.write( " $\"%28-7%2B3%29%5E2=16\"$
\n" ); document.write( " $\"%28-4%29%5E2=16\"$
\n" ); document.write( " $\"16=16\"$ x=-7/3 also check out, so we're right!!!
\n" ); document.write( "Happy Calculating!!! \n" ); document.write( "
