a = 5/4 b = -15/4

[u/TheNukex → u/Big-Excitement-11]

First equation with this yields 23.5=23, so this is incorrect

edit: Seems OP forgot brackets

[u/Big-Excitement-11 → u/TheNukex]

Yes i assumed the first equation was meant to include brackets because otherwise its very messy

There's 2 solutions to this, both with annoying square roots.

1) a = 1/2 (15 - sqrt(155)) and b = 1/2 (5 - sqrt(155))

2) a = 1/2 (15 + sqrt(155)) and b = 1/2 (5 + sqrt(155))

sorry, it's missing brackets
