You can put this solution on YOUR website!
Solve:
\n" ); document.write( "\"25x%5E2%2B49+=+0\"
\n" ); document.write( "You're on the right track!
\n" ); document.write( "\"25x%5E2%2B49+=+0\" Subtract 49 from both sides.
\n" ); document.write( "\"25x%5E2+=+-49\" Take the square root of both sides.
\n" ); document.write( "\"sqrt%2825x%5E2%29+=+sqrt%28-49%29\"
\n" ); document.write( "\"5x+=+7sqrt%28-1%29\" or \"5x+=+-7sqrt%28-1%29\" Divide both sides by 5.
\n" ); document.write( "\"x+=+%287%2F5%29sqrt%28-1%29\" or \"x+=+%28-7%2F5%29sqrt%28-1%29\" which can also be expressed as:
\n" ); document.write( "\"x+=+%287%2F5%29i\" or \"x+=+-%287%2F5%29i\" where: \"i+=+sqrt%28-1%29\"
\n" ); document.write( "There are no real solutions.
\n" ); document.write( "
\n" );
