Solve for x:
\n" ); document.write( " $\"x-13%2Asqrt%28x%29%2B40+=+0\"$ Add $\"13sqrt%28x%29\"$ to both sides.
\n" ); document.write( " $\"x+%2B+40+=++13sqrt%28x%29\"$ Square both sides..
\n" ); document.write( " $\"x%5E2%2B80x%2B1600+=+169x\"$ Subtract 169x from both sides.
\n" ); document.write( " $\"x%5E2-89x%2B1600+=+0\"$ Solve the quadratic equation by factoring.
\n" ); document.write( " $\"%28x-25%29%28x-64%29+=+0\"$ Apply the zero product property: If a*b = 0, then either a = 0 or b = 0 or both.
\n" ); document.write( " $\"x-25+=+0\"$ or $\"x-64+=+0\"$ so...
\n" ); document.write( " $\"x+=+25\"$ or $\"x+=+64\"$ \n" ); document.write( "

\n" );
