Just wondering if you could check my working for me below. I *think* it's right but when I put it in on an equation calculator to check and it seems to think that x is just 0 but that might just be it only giving one value (origin). Regardless, I'm mainly interested in whether I re-arranged it for x correctly and factorised it correctly, not just the answer.
Question:
Working:
This was just the start of the question for finding the area bound by the curve and the line which I have done, but was unsure here (on the easier bit hehe
) for some odd reason.
Anyway, thanks for any help. I know it can also factorise to x(x-4) if you do the steps a bit differently at the start by doubling to get 1 whole x, squaring both sides and then re-arranging. That also gives 4 but I just wanted to check.
Yeah it's a bit basic, sorry, but thanks for checking. Oh and by sqr. I mean square root if that's not clear.
Not sure if this was the right board on here to post it on but cheers.
