Answer:

-2 $\sqrt{10$ +5

Step-by-step explanation:

The square root of 25 is 5. Perfect squares get taken out of the square root signs. 40 isn't a perfect square root so it breaks down into 2 and square root10. It is being subtracted so by a bigger number so it is going to be negative. Sorry if my explaining ins't the best. Good luck! I know math is SUPER hard. :)
