One integer is 18 more than twice another number,
\n" ); document.write( "a = 2b + 18
\n" ); document.write( " if their product is equal to -36, what are the integers?
\n" ); document.write( "a*b = -36
\n" ); document.write( "Therefore
\n" ); document.write( "b(2b+18) = -36
\n" ); document.write( "2b^2 + 18b + 36 = 0
\n" ); document.write( "simplify, divide by 2
\n" ); document.write( "b^2 + 9b + 18 = 0
\n" ); document.write( "Factors to
\n" ); document.write( "(b+3)(b+6) = 0
\n" ); document.write( "Two solutions
\n" ); document.write( "b = -3
\n" ); document.write( "b = -6
\n" ); document.write( "then when b = -3
\n" ); document.write( "a = 2(-3) + 18
\n" ); document.write( "a 12
\n" ); document.write( "when b = -6
\n" ); document.write( "a = 2(-6) + 18
\n" ); document.write( "a = 6
\n" ); document.write( " Give one of the two pairs of numbers for which this is true.
\n" ); document.write( "a=12, b=-3 or a=6, b-6\r
\n" ); document.write( "
