Pearson Edexcel Mark Scheme (results) GCE In Mathematics (9MAO) Paper 2 Pure Mathematics 2 General Principles for Further Pure Mathematics Marking (But note that specific mark schemes may sometimes ... override these general principles) Method mark for solving 3 term quadratic: 1. Factorisation (x 2 + bx + c) = (x + p)(x + q), where pq = c , leading to x =... (ax2 + bx + c) = (mx + p)(nx + q), where pq = c 2. Formula and mn = a , leading to x =... Attempt to use the correct formula (with values for a, b and c) 3. Completing the square x 2 +bx +c = 0  b  2 = Solving :  x      q  c = 0, q  0 , leading to x ... Method marks for differentiation and integration: 1. Differentiation Power of at least one term decreased by 1. 2. Integration Power of at least one term increased by 1. (x n → x n−1 ) (x n → x n+1 ) [Show More]
