    (i) 9x^2 - 12x + 5 9(x^2 - 4/3x + 5/9) 9((x - 2/3)^2 + 1/9) 9(x - 2/3)^2 + 1 -> 1(3x - 2)^2 + 1 (ii) d(3x^3 - 6x^2 + 5x - 12) / dx 9x^2 -12x + 5 = 9(x - 2/3)^2 +1 f'(x) always > O so increasing function.

    Mj12 3) First three terms of expansion of (1 + ax)^6 = 1 + 6ax + 15a^2x^2 Expanding (1 - 2x)^2 = 4x^2 - 4x + 1 Multiply both to get x^0 term, x^1 and x^2 term. x^0 = 1 x^1 = -4x + 6ax x^2 = -24ax^2 + 4x^2 + 15a^2x^2 We know coffiecients x^0 = 1 x^1 = -1 x^2 = b x^1 : -4 + 6a = -1 ; a =...
