Question

How do I factorise 5a2 + 6ab

2 is squared

Answer 1

a(5a+6b) I think that's it. Take out any common factors (in this case a) and that goes outside the brackets when it can't be factorised into two or more brackets. Everything that goes in the brackets has been divided by the common factor. I don't know if what I'm saying makes sense, I'm new to this. Sorry.

Answer 2

a(5a + 6b).
Because a is the thing both terms have in common, and the numbers inside the brackets are the terms you need to multiply by a to get 5a2 and 6ab.
Hope this helps!
