I suppose since you've already got an A^ in further maths, your teacher is giving you the even bigger challenge of getting 100% on a set of MathsWatch proof exercises

PRSOM I doubt many people would have had the patience to help Loci Pi get to 100%.
I sensed and shared the frustration of a poor system

Probably! The mathswatch proofs were definitely harder.

Try expanding the brackets out fully (for example x^2 +5x +5x +25 then simplifying)

Try adding a new sentence at the end (Hence [insert expression from the beginning] is a multiple of 4 for all positive integer values of n)

If the question says multiple, use the word multiple in your answer. If the question says divisible, use the word divisible in your answer. MathsWatch is fussy like that.

Good luck

Edit: Also try removing words like simplify, you only need the algebra and the sentences at the end I think.

Thanks It's still not working so I think I will just have to explain to my teacher tomorrow.

Maybe try using the difference of two squares instead.

(n+5)^2 - (n+3)^2

= (n + 5 + n + 3)(n + 5 - n - 3)
= (2n+8)(2)
= 4(n+4)

No it doesn't they can view your work and answers at any point, it doesn't have to be 100%

Maths Watch only says submitted automatically once you have got 100%, but it submit automatically on the deadline regardless of the %. My teacher didn't say whether or not she could see our answers at any point; I hope teachers haven't seen some of my silly mistakes when I didn't read the question properly lol

Can anybody figure out what the problem with this is? It's the last grade 7 question I need to do
Attachment 696828
Maybe do the (2n+1)^2 and (2n-1)^2 in the same line, not separate lines?

I have just done a homework and it marked my answer wrong but I know it is right. I typed it in correctly so I have no idea why it said it is wrong. If anyone can find the solution, please let me know.Thanks
Can you post a photo of the question and your working? Maths watch is very fussy with the working out lol

Why is my last post comment under review? What did I do wrong? All I did was ask for the MathsWatch question.
