You're on the right track, but you forgot to square the 15!
\n" ); document.write( "\"15+=+%28x%5B2%5D+-+10%29%5E2+%2B+81\" <-------- This is what you have
\n" ); document.write( "\"15%5E2+=+%28x%5B2%5D+-+10%29%5E2+%2B+81\" <------- This is what you should have
\n" ); document.write( "\"225+=+x%5B2%5D%5E2+-+20x+%2B+100+%2B+81\"
\n" ); document.write( "Continue to solve for \"x%5B2%5D\" from here. You should get 2 values for \"x%5B2%5D\", but one is positive and the
\n" ); document.write( "other is negative. You need the negative value since K is in the 2nd quadrant, where x is negative. \n" ); document.write( "
