Question

find the hcf of 3(a-5) and 12(a²-25)​

Answer 1

Answer:

3(a-5)

Step-by-step explanation:

12(a²-25)=3(a²-5²)=3*4*(a-5)(a+5)

so hcf is 3(a-5)

Answer 2

Answer:

3(a-5)

Step-by-step explanation:

From the first expression we simply have 3(a-5) .

From the second expression we have =3×4 (a+5)(a-5)

So the highest common factor from the above two expressions is 3(a-5) , that is common in both .
