Question

How do you factor `8(1+y)+2y(1+y)`?

Answer 1

`2(4(1+y)+y(1+y))`

Explanation:

The way to factorise an expression is to look at all the terms and see if they have any common factors.

In this case, the terms we have are `8(1+y)` and `2y(1+y)`. They can both be rewritten as `2(4(1+y))` and `2(y(1+y))`. Both of these terms have a common factor of `2`, so we simply take `2` out of the expression as a factor of both terms.
