[eternal dragon]

yeah thats what i got

holup let me try to get a pic

ignore the black lines

the last step is incomplete

what mistake did i make

[limpid dune]

You didn't expand the brackets correctly in the denominator.

[harsh mantle]

yeah it's hard to tell

you just got something random instead, try again

[limpid dune]

You expanded it as a square when it's not.

[eternal dragon]

best i can do

[eternal dragon]

which step

[limpid dune]

Second to third line

[harsh mantle]

(√3)(√3+√5) -(√5)(√3+√5)
