प्रश्न 1.
गुणनखण्ड कीजिए-
(i) 12x + 36
(ii) 22y – 33z
(iii) 14pq + 35 pqr
हल:
(i) 12x = 12 × x और 36 = 12 × 3
∴ 12x + 36 = (12 × x) + (12 × 3)
= 12(x + 3)

(ii) 22y = 11 × 2 × y और 33z = 1 1× 3 × z
∴ 22y – 33z = (1 1 × 2 × y) – (11 × 3 × z)
= 11 × (2 × y – 3 × z)
= 11(2y – 3z)

(iii) 14pq = 7 × 2 × p × q
और 35pqr = 7 × 5 × p × q × r
∴ 14pq + 35pqr = (7 × 2 × p × q) + (7 × 5 × p × q × r)
= 7 × p × q × (2 + 5 × r)
= 7pq (2 + 5r)

(i) 24xy2z3 को 6yz2 से
(ii) 63a2b4c6 को 7a2b2c3 से
हल:
(i) 24xy2z3 + 6yz2
= $$\frac{6 \times 4 \times x \times y \times y \times z \times z \times z}{6 \times y \times z \times z}$$
= $$\frac{4 \times x \times y \times z}{2}$$
= 4xyz

(ii) 63a2b4c6 ÷ 7a2b2c3
= $$\frac{7 \times 9 \times a \times a \times b \times b \times b \times b \times c \times c \times c \times c \times c \times c}{7 \times a \times a \times b \times b \times c \times c \times c}$$
= 9 x b2 x c3 = 9b2c3
