Until your instructor (or the textbook) gives you any instructions, there isn't anything to "do".

By the way, did the other reply correctly guess your meaning? Is the square root around everything, so you meant "sqrt[10x^2 + 100x + 250]", or does the root end sooner, so maybe it's just "sqrt[10]x^2 + 100x + 250", like you posted? Thank you!
