Let x be the number;
\n" ); document.write( " $\"x%5E2\"$ -14=5x
\n" ); document.write( "Now but this in standard form;
\n" ); document.write( " $\"x%5E2\"$ -5x-14=0
\n" ); document.write( "Now factor;
\n" ); document.write( "(X+2)(x-7)=0
\n" ); document.write( "x+2=0
\n" ); document.write( "x=-2
\n" ); document.write( "x-7=0
\n" ); document.write( "x=7
\n" ); document.write( "So x=-2 or x=7
\n" ); document.write( "When you plug each oneinto the equation you find;
\n" ); document.write( "x=7
\n" ); document.write( "=) \n" ); document.write( "
