2.
(a) Remove the brackets and simplify
(i) 4(3 – 2p) - 3(1-p),
(ii) (39 - r)q + 2r).
(b) Factorise completely 18t2 – 2.
(c) Given that y = 18 + 3x2,
(i) find the value of y when x = -2,
(ii) find the values of x when y = 93,
(iii) express x in terms of y.

Answer 1

Answer:

i) 4(3 - 2p) - 3(1-p)

12 - 8p - 3 - 3p

12 - 3 - 8p - 3p

9 - 5p = 9 - 5p
