wtf is this quadratic equations

Declined:

Even though maths is my favourite subject, I am only in 10th grade (Year 10).

So Chye is very likely to be 15-16 y/o (sorry if I'm wrong I found the info on Wikipedia)

well, thats correct. Australia year 10 = UK year 11 btw

are calculators allowed for this?

And? I am your same age and I have no problems with this question (except ok thats unfair because I am ahead of the educational system by 3 years)

im like ms schooler and i can do harder problems than this

Translation: Geometric sequence satisfies the 2 conditions above.

Find the sum of all integers M satisfying the inequality below.

but a) (x-2)(x^2-4x-1)

b) i) 2-5^(1/2)

b) ii) 2+5^(1/2)

c) I won't justify (unless you request me to) but since two solutions are greater than 1 and are therefore outside the range of the sine wave, there are two solutions between -pi and 0 and 6 solutions between 0 and 12pi, so 8 solutions in total.

Positive integers?

yes

Well okay, for positive integers it should be 25, but i might be wrong

Wait i think i messed something

Ok i did but that doesn't change the answer i think

Is 25 correct or wrong? (Numbers 1, 3, 5, 7, 9)

it is correct!

how old are you btw

Prove infinite primitive integer triplets (x, y, z) satisfy the equation above with all natural numbers n.

Primitive means a solution cannot be shrunk down to just it's factors, no requirement states it shall be coprime.

Not really important

Can you rephrase the question?

As in are you an adult, kid or teen? Adult = 18+
