Question

a+1 over 6 = 2/a what is a

Answer 1

\[(a+1)/6=2/a\]
multiply both sides by 6a
what would you get?

Answer 2

6a^2+1 = 12a^2

Answer 3

a(a+1)=12
a^2 +a-12=0
use quadratic formula to find a
what did you get for a?

Answer 4

3

Answer 5

or you can re-write it as:
(a+4)(a-3)=0
(i used quadratic formula to find roots... honestly...)
so, the answer would be:
a=3 and a=-4

Answer 6

are you good?
