Question

HCF of 9 a square minus 16 b square and 12a square minus 16 ab is

Answer 1

Step-by-step explanation:

9a^2 - 16b^2= (3a+4b)(3a-4b) since a^2-b^2=(a+b)(a-b)

12a^2-16ab= 4a(3a-4b)

There is a common factor 3a-4b in both expressions.

So, it is the HCF

Answer 2

Answer:

Step-b9a^2 - 16b^2= (3a+4b)(3a-4b) since a^2-b^2=(a+b)(a-b)

12a^2-16ab= 4a(3a-4b)

There is a common factor 3a-4b in both expressions.

So, it is the HCFy-step explanation:
