So let's multiply both values. Remember that in multiplying this, what we are going to do with the exponents is just to add them.
So 5x^2 (2x^2) = 10x^4
     5x^2 (13x) = 65x^3
     5x^2 (-5) = -25x^2.
Therefore, the product is 10x4 +65x3-25x2. Hope this is the answer that you are looking for. Let me know if you need more help next time.
