Factorise fully the following expression: 2a^(2)b + 6ab^(2)

Factorise fully the following expression: 2a²b + 6ab²
First, find the common terms by treating, 2a²b and 6ab² as separate objects.
We see common terms of... 2, a, and b
We notice that 2aba = 2a²b and that 2ab3b = 6ab²
Hence we can rewrite the function: 2a²b + 6ab² = 2ab(a+3b)
