Here the factors are (y 10 ( y 10) and (y −10) ( y − 10) 3 Using Identity (xa) (xb) Sometimes, it is possible to express a quadratic equation in the form (x a)(x b) ( x a) ( x b) Let's understand this through an example Example x2−5x 6 = 0 x 2 − 5 x 6 = 0A (2x 4y) C (2x 4y) B (2x 4y)(2x 4y) D (2x 4y)(2x 4y) 9 What are the two numbers whose sum is 1 and whose product is 12?Question Working Answer Mark Notes 1 180 2 2 3 3 5 = 198 2 3 3 11 = or 2 180 198 3 90 99 3 30 33 2 10 11 5 5 11 11 1 11 1 1 2 M1 A correct method to enable the LCM to be found Correct factorisation of 180 and 198 allow on factor trees For the table they must divide both numbers by those shaded (or other combination with a product of 18) in grey at some point All other lines are optional but
