You can put this solution on YOUR website!
Solve using the square root property:
\n" ); document.write( "(x + 4)^2 = 81
\n" ); document.write( "This means taking the square root of both sides. When you do this, you have to remember to include the + or -:
\n" ); document.write( " $\"%28x%2B4%29=0+%2B-+9\"$
\n" ); document.write( " $\"+x=-4+%2B-+9\"$
\n" ); document.write( " $\"x=-4%2B9\"$ or $\"x=-4-9\"$
\n" ); document.write( " $\"x=5\"$ or $\"x=-13\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Solve by completing the square:
\n" ); document.write( " $\"x%5E2+%2B+6x+%2B+2+=+0\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x%5E2+%2B+6x++=+-2\"$
\n" ); document.write( " $\"x%5E2+%2B6x%2B9=-2%2B9\"$
\n" ); document.write( " $\"%28x%2B3%29%5E2=7\"$
\n" ); document.write( " $\"%28x%2B3%29=0%2B-+sqrt%287%29\"$
\n" ); document.write( " $\"+x=-3%2B-sqrt%287%29\"$ \r
\n" ); document.write( "
