Answer 1

Answer:

Q1

a) 14 pq , 28 p^2q^2

14 pq = 2×7×p×q

28 p^2q^2 = 2×2×7×p×p×q×q

common factor : 2×7×p×q = 14pq

b) 12x, 16

12x = 2× 2 × 3× x

16 = 2 × 2 × 2× 2 × 2

common factors : 2×2 = 4

c) 10 pq , 20 qr , 30 rp

10pq = 2×5×p×q

20qr = 2×2×5×q×r

30rp = 2× 3×5 × r× p

common factor = 2×5 = 10

Q2

a) 20l^2m + 30alm

= 10 lm ( 2l + 3a)

b )5x^2y - 15 xy^2

= 5xy ( x - 3y )
