Answer: 5(4x² + 4x + 1)

Assuming it wants us to simplify it:

Find the common multiple all the numbers have. You can see both 20s have an x but 5 doesnt, so we cannot take that out. However, 5 and 20 are in the 5 times table, So we can take that out and put it outside a bracket.

You then divide 20x², 20x and 5 by 5, which gives us:

5(4x²+4+1)

Since this cannot be simplified any further, this is the answer.

Assuming it wanted us to factorise this.
