Solve for x:
\n" ); document.write( " $\"x%5E2-4x+=+6\"$ Complete the square in x by adding the square of half the x-coefficient to both sides of the equation. That's $\"%28-4%2F2%29%5E2+=+4\"$
\n" ); document.write( " $\"x%5E2-4x%2B4+=+6%2B4\"$ Factor the left side and simplify the right side.
\n" ); document.write( " $\"%28x-2%29%5E2+=+10\"$ Take the square root of both sides.
\n" ); document.write( " $\"%28x-2%29+=+sqrt%2810%29\"$ or $\"%28x-2%29+=+-sqrt%2810%29\"$ Add 2 to both sides of each solution.
\n" ); document.write( " $\"x+=+2%2Bsqrt%2810%29\"$ or $\"x+=+2-sqrt%2810%29\"$ \n" ); document.write( "
