Question

is this simplified? [-26+ - 2sqrt(163)]/-6
or could I simplify it to [-13+ - sqrt(163)]/-3
or does the negative cancel out so it would be [13 + - sqrt(163)]/3??

Answer 1

i hate simplifying. I never know when I am done!

Answer 2

We have
\[\frac{-26+-2\sqrt{163}}{-6}\]
first cancel 2 from numerator and denominator
\[\frac{-13+-\sqrt{163}}{-3}\]now this can be written as
\[\frac{-13-\sqrt{163}}{-3}\]
remove" - "from all the terms
\[\frac{13+\sqrt{163}}{3}\]

Answer 3

ok. thank you, but wouldn't the "+-" still be there? not just "+"

Answer 4

\[+ \times -=-\]

Answer 5

but its still a square root, which could be both positive or negative numbers

Answer 6

oops I got your point then
\[\frac{13\pm\sqrt{163}}{3}\]

Answer 7

yeah you're right :)

Answer 8

:)

Answer 9

aren't there still 2 answers... as it can be split

\[\frac{-26}{-6} \pm \frac{\sqrt{163}}{-6} = \frac{13}{3} \mp \frac{\sqrt{163}}{3}\]
