Find two consecutive negative integers whose product is 90
\n" ); document.write( ".
\n" ); document.write( "Let x = first negative answer
\n" ); document.write( "then
\n" ); document.write( "x+1 = second negative answer
\n" ); document.write( "x(x+1) = 90
\n" ); document.write( "x^2 + x = 90
\n" ); document.write( "x^2 + x - 90 = 0
\n" ); document.write( "(x+10)(x-9) = 0
\n" ); document.write( "x = (-10, 9)
\n" ); document.write( "Since we're looking for a negative answer, throw out the positive answer leaving:
\n" ); document.write( "x = -10 (first negative number)
\n" ); document.write( ".
\n" ); document.write( "Second negative number\"
\n" ); document.write( "x+1 = -10+1 = -9
\n" ); document.write( ".
\n" ); document.write( "Answer: -10 and -9 \n" ); document.write( "
