Hi Jack!


15.25 you could have factored out 2 as the coefficients had a factor of 2. But why didn't you? Please shed some light on this thanks.

How can you write 8x + (2x+2)^4 = as 10 x + 4?, I believe at 15:06 you forgot the index 4 and wrote just 2(x+2) instead of 2(x+2)^4.

Is it ok to divide the top and the bottom of a fraction by (x-2) for example in a function? Would this lose solutions like with a polynomial?

Could you do explain how to differentiate (x^1/2)/(1+x^1/2)?

Hello, I think question 3, there was a mistake as you put it to the power of 4 instead of 2.
