#

Idk any other way but you already have one root right? a + b

#

Actually

#

Ignore that

thin python
#

oh yea

#

calm

neon drift
#

We don’t have a cubic

thin python
#

wait why wouldnt itwok

neon drift
#

We don’t have the cubic

#

To divide

#

I was being dumb

thin python
#

oh lol

#

should I substitute?

#

for example i know alpha beta = 5/2

#

so alpha = (5/2)/beta

winter torrent
#

u know what alpha + beta is

#

And u know the original quadratic has roots alpha an dbeta

#

So do the (orginal quadratic)(z-(alpha+beta))

#

and expand out

thin python
#

oh damn

#

thanks

#
