Question

Plzzzzzzzzzzzzzzzzzzzzzz find the hcf of 15a²b² and -24ab

Answer 1

3ab

Explanation:

`15a^(2) b^(2) - 24ab` is divided by 3

`5a^(2) b^(2) - 8ab` take away a and b once

hope this helped!!!

`5ab - 8`

= 3ab

Answer 2

Let's take a look at each term separately.

15a^2b^2:

15 has factors 1, 3, 5, 15

a x a

b x b

-24ab

-24 has factors 1, 2, 3, 4, 6, 8, 12, 24

a

b

Now, we can see what each of these terms has in common. Both have a 3 in their factor lists, as well as one a and one b.

Therefore, the greatest common factor is 3ab.

Hope this helps!! :)
