You can put this solution on YOUR website!
Let x be the unknown number.
\n" ); document.write( ".
\n" ); document.write( "Then twice the square of this number is $\"2x%5E2\"$
\n" ); document.write( ".
\n" ); document.write( "15 times the number is $\"15x\"$ . Subtracting this from twice the square of the number is:
\n" ); document.write( ".
\n" ); document.write( " $\"2x%5E2+-+15x\"$
\n" ); document.write( ".
\n" ); document.write( "And you are told that this has to equal -27.
\n" ); document.write( ".
\n" ); document.write( "Therefore, the equation you are looking for is:
\n" ); document.write( ".
\n" ); document.write( " $\"2x%5E2+-15x+=+-27\"$ .
\n" ); document.write( ".
\n" ); document.write( "Just in case you work out this equation, it has two solutions ... $\"x+=+9%2F2\"$ and $\"x+=+3\"$
\n" ); document.write( ".
\n" ); document.write( "Hope this is of some assistance to you. \n" ); document.write( "
