Find two integers whose sum is -7
\n" ); document.write( "a + b = -7
\n" ); document.write( "b = -a - 7
\n" ); document.write( " and whose product is 12.
\n" ); document.write( "ab = 12
\n" ); document.write( "replace b with (-a - 7)
\n" ); document.write( "a(-a-7) = 12
\n" ); document.write( "arrange as quadratic equation
\n" ); document.write( "-a^2 - 7a - 12 = 0
\n" ); document.write( "multiply equation by -1, get rid of all those negatives
\n" ); document.write( "a^2 + 7a + 12 = 0
\n" ); document.write( "Factors to
\n" ); document.write( "(a+3)(a+4) = 0
\n" ); document.write( "a = -3, then b = -4
\n" ); document.write( "or
\n" ); document.write( "a = -4, then b = -3 \n" ); document.write( "

\n" );
