Question

Factorise each of the following polynomial by taking out common factor.

a) 12a² - 14a

b) a³ - a² + a

c) 65 ( a + b)² - 13 ( a + b)³

d) 18p²q - 24pqr ​​

Answer 1

Answer:

Solution :-

a) 12a² - 14a

↦ 2a(6a - 7)

∴ The answer of this question is 2a(6a - 7)

b) a³ - a² + a

→ a(a² - a + 1)

∴ The answer of this question is a(a² - a + 1)

c) 65(a + b)² - 13(a + b)³

➞ 13(a + b)² (5 - a + b)

∴ The answer of this question is 13(a + b)² (5 - a + b)

d) 18p²q - 24pqr

→ 6pq(3p - 4r)

∴ The answer of this question is 6pq(3p - 4r)
