No. Because you wouldn’t be squaring a equation. You’d just be saying the binomial expansion of “1/sqrt(x)” is the same as the binomial expansion “1/x” (if you just squared the expression), which it’s not. I assume that’s what you’re asking. I mean try it and then expand it out, you won’t get the same answer. :)

Cant we Square the whole equation to remove the square root in question 1 ?

Started integration just putting it together so those videos will be coming out very soon. After that I will begin complex numbers and vectors. I’m sorry they take a while I just really want to organise everything correctly. I have to be thinking not just about the current students on here but also students years down the line. Thank you for your patience and support. Please remember you can ask me questions on Instagram as well :)
