Probably the easiest way to solve this equation is by factoring. Since both terms on the left
\n" ); document.write( "side contain an x, you can factor out an x to give:
\n" ); document.write( ".
\n" ); document.write( "x*(x - 14) = 0
\n" ); document.write( ".
\n" ); document.write( "This equation will be true if either of the factors on the left side are zero because a
\n" ); document.write( "multiplication by zero on the left side will make the left side equal the zero on the right side.
\n" ); document.write( ".
\n" ); document.write( "So we can get the two answers by setting each of the factors equal to zero.
\n" ); document.write( ".
\n" ); document.write( "For the first factor equal to zero we have:
\n" ); document.write( ".
\n" ); document.write( "x = 0 and that is one answer.
\n" ); document.write( ".
\n" ); document.write( "For the second factor equal to zero we have:
\n" ); document.write( ".
\n" ); document.write( "x - 14 = 0
\n" ); document.write( ".
\n" ); document.write( "And if we add 14 to both sides we get:
\n" ); document.write( ".
\n" ); document.write( "x = 14 and that is the second answer.
\n" ); document.write( ".
\n" ); document.write( "Check ... go to the original equation x^2 - 14x = 0 and substitute 0 for x. The result is:
\n" ); document.write( ".
\n" ); document.write( "0 - 0 = 0
\n" ); document.write( ".
\n" ); document.write( "and that is a correct equation, so the answer x = 0 checks.
\n" ); document.write( ".
\n" ); document.write( "Return to the original equation x^2 - 14x = 0 and substitute 14 for x. When you do you get:
\n" ); document.write( ".
\n" ); document.write( "14^2 - 14*14 = 0
\n" ); document.write( ".
\n" ); document.write( "and since 14^2 = 14*14 the equation becomes:
\n" ); document.write( ".
\n" ); document.write( "14*14 - 14*14 = 0
\n" ); document.write( ".
\n" ); document.write( "This also is a correct equation so the answer x = 14 checks.
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you to understand the problem.
