2x2 - 9x + 4 you do 4 muliply to 2 to get the factors ok which can be multiplied to give 8 and add/subtract to give -9x. OK!!!!! Factors of 8 are: 2 X 4 but it doesnt add upto give 9 so -8 and -1 give -9 when added ok!!!! 2x2 -8x -1x + 4 take common factors 2x(x - 4) - 1(x - 4) (x-4) is common so take one out and other from ooutside brackets Answer 2x2 - 9x + 4 you do 4 muliply to 2 to get the factors ok which can be multiplied to give 8 and add/subtract to give -9x.
