Algebra.Com's Answer #30766 by corrie21(4)![]() ![]() ![]() You can put this solution on YOUR website! Since x^2 will be the first to factor you make two sets of parathesis and put x as the first factor in each \n" ); document.write( "(x )(x ) \n" ); document.write( "Next you have to figure out which numbers that make -18 will also come out to a -3 when you add or subtract. \n" ); document.write( "For example, the factors of 18 are 1, 2, 3, 6, 9, 18. Which of those numbers could make a negative 3? A negative 6 and a positive 3 will make a -3 when you add them, and it will make a -18 when you multiply them. So heres how you finish the problem... \n" ); document.write( "(x-6)(x+3) \n" ); document.write( "To check your answer, FOIL it out. \n" ); document.write( " |
