1.2 EXPANSION AND FACTORIZATION
1. Expand and simplify the following.
a) (2 – n)2 – n(n – 3) b) , r ≠ 0.
c) m2 + (4k + m)(4k - m) d) 3(p – 2)2 + 1 – 3p2
e) 6(b – 3) – 3(b – 1) f) (a + 2)2
2. Factorize the following :
a) 18x + 27 d) x2(x – 3) + 12(x – 3)
b) 4x2 – 8x e) x2 + 8x +15
c) 9x4 – 18x3 – 27x2 f) 6x2 – 17x + 12
