You can put this solution on YOUR website!
If 9x^2 - y^2 = 0 then what is the positive value of the x/y ?
\n" ); document.write( ".
\n" ); document.write( "Notice, I can rewrite:
\n" ); document.write( "9x^2 - y^2 = 0
\n" ); document.write( "as
\n" ); document.write( "(3x)^2 - y^2 = 0
\n" ); document.write( ".
\n" ); document.write( "This is a \"difference of squares\", so I can factor as:
\n" ); document.write( "(3x-y)(3x+y) = 0
\n" ); document.write( ".
\n" ); document.write( "The positive value of x/y is then:
\n" ); document.write( "3x-y = 0
\n" ); document.write( "3x = y
\n" ); document.write( "x = y/3
\n" ); document.write( "x/y = 1/3 (this is your answer)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
