Anyone help with e?

[bronze socket]

,rotate

[little pilot]

Yes

[little pilot]

Damn is the working out that long

[bronze socket]

alpha^(n + 1)
= alpha^n * alpha
= (a * alpha + b) * alpha
= a * alpha² + alpha * b
= (a * alpha)alpha + alpha * b
c = a * alpha
d = b * alpha
cd = ab * alpha²
cd/ab = alpha²
alpha^(n + 3)
= alpha^(n + 1) * alpha²
= (c * alpha + d) * cd/ab
= (c²d/ab) * alpha + cd²/ab
I just got it till here

[little pilot]

oh

Alrighr

[little pilot]

Wait

But isn’t

It a * alpha

Since bracket expansion

[bronze socket]

which part?

[little pilot]

Oh wait

Yes I see it

Why does cd/ab = alpha ^2?

[bronze socket]

cuz cd = ab * alpha²

[little pilot]

Wait
