Expand 4x(x+2)

For this type of question, we always simply take the term outside the bracket and multiply it with the terms inside the bracket sequentially. So, first we evaluate 4x * x, which gives us 4x2. Next, we evaluate 4x * 2, which gives us 8x. We therefore end up with the answer as '4x2 + 8x'.
