Please explain in the most basic way. I really don't understand where the 1/4 comes from. I really don't understand anything

I don't understand why I'm stuck.

This is binomial expansion. I know the coefficient of x^2= 24. I end up with: 3/4ax^2 / 2! = 24 which I simplified to ax^2 =64. Answer says a= +-8. Why ?

Thank you

I really like my friend, but she has another best friend who shes known for ages, and im a bit jealous of their relationship. I have never had a beset friend I can go to whenever and have a laugh (acc, ive had a lot of problems when it comes to friendship) so im really jealous of her being with her friend. What can I do?!

why are there 3 answers and not 2!??!!! I only got +- 54.7 but there is the answer -125.3 degrees aswell!! heres my working out:

tanx = 2/tanx

tan^2x = 2

tanx = sqrt 2

therefore: tan-1 (sqrt2) = 54.7

and tan-1 (sqrt -2) = 54.7

the answer says -125.3 ....where did they get that from?!

At the end of harry potter and the deathly hallows part 2, where we see them 19 years later in the future, there is this soundtrack that plays at the end, sort of happy, triumphant AND it plays at the end of every film really...anyway, does anyone know what it is called? Links please welcome!

I have to work out the equation of a line joining two points. They are: (-2,5) and (5,3)

I worked out the gradient is: -2/6. I then have to write in the form ax+bx+c=0.

How do I do that?!

I did: 5= -2/6(x-1) +c

which is: 5= 2/6 +c

which is: c=5-2/6 = 28/6

So I got the equation: y= -2/6x+28/6

How do I then get rid of the 6's at the bottom?

Don't you have to times the whole equation by 6? But im not sure how many times? Just once or twice? Because I timed it once and the answer was wrong :( Please help!!!
