I DETEST these types of problems that DON'T have INTEGER solutions.\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "x - y = 2______x = 2 + y ------- eq (ii)
\n" ); document.write( "\"%282+%2B+y%29%5E2+%2B+y%5E2+=+3\" ------- Substituting 2 + y for x in eq (i)
\n" ); document.write( "\"4+%2B+4y+%2B+y%5E2+%2B+y%5E2+=+3\"
\n" ); document.write( "\"2y%5E2+%2B+4y+%2B+4+-+3+=+0\"
\n" ); document.write( "\"2y%5E2+%2B+4y+%2B+1+=+0\"
\n" ); document.write( "Using the quadratic equation formula, or Completing the Square, solve for y.
\n" ); document.write( "You should get 2 different values for y, which are: \"highlight_green%28matrix%281%2C3%2C+%22-+0.292893219%2C%22%2C+and%2C+-+1.7071%29%29\"
\n" ); document.write( "Substitute each value for y into any of the 2 ORIGINAL equations (2nd equation is EASIER) to get the 2 corresponding values for x.
\n" ); document.write( "There you have it! All done!! \n" ); document.write( "
