Hello,
I have a question about problems like these. Here is the question
√23-√37 / √23+√37
I multiplied the denominator by √23-√37 which after simplifying gave me:
60-2√851 / -14
In this instance, as the denominator is negative, should I multiply by -1 and then divide by 2 to leave me with:
√851-30 / 7
Or shouldn't I have multiplied by -1, leaving the denominator as a negative? Your help is greatly appreciated!
