    M1 for (–11)2 + 82 oe

  • 10(b)(i)[3]

    a + 3 5 (b – a) or b + 2 5 (a – b) leading to 2 5 a + 3 5 b with no errors [6]

    M3 =] 3 5 (b – a) oe

    M2 for [ MR = ] 2 5 (a – b) oe or [ NR = b – a or NM = a – b

    or M1 for MN or a correct route for OR

  • 10(b)(ii)[5]

    k = 5, c = 10 [4]

    B2 for c = 10

    or M1 for c( 2 5 a + 3 5 b) = b + 4a + kb oe or for 2 5 c = 4 and
