Question

When solving for a in -8+square route of (5a-5)=-3, do I square -8 when i get rid of the square route, and if so does it become 64 or -64?

Answer 1

add 8 first!

Answer 2

otherwise you will have a mess.
\[-8+\sqrt{3a-5}=-3\]
\[\sqrt{3a-5}=5\] etc

Answer 3

first add 8, then square, then solve

Answer 4

oh thanks i completely forgot about adding the 8!

Answer 5

then check

Answer 6

oh damn ignore my answer. i used
\[3a-5\] instead of
\[5a-5\] sorry

Answer 7

that's fine i can solve it now that i know to add the 8. thanks!

Answer 8

\[\sqrt{5a-5}=5\]
\[5a-5=25\]
\[5a=30\]
\[a=6\] is more like it
