Question

Write the HCF of the terms of each of the following expressions:

(i) a^3b+a^2b^4+ab^3

(ii) 4x^5+6x^3-8x^2+14x^4

(iii) -15mn^2p^3+25m^3n^2p-35m^4n^4

(iv) 36a^5-90a^4+54a^3-18a^2

Solution

1. a^3b+a^2b^4+ab^3 = ab

2. 4x^5+6x^3-8x^3+14x = 2x^3

3. -15mn^2p^3+25m^3n^2p-35m^4n^4= HCF = 5mn^2

4. 36a^5-90a^4+54a^3-18a^2

**HCF is =6a^2**
