Question

I have a homework paper about simplifing an expression and stating excluding values. I know how to simplify but how does it work with the excluding values?
Thank you.

Answer 1

make sure the denominator is not zero

Answer 2

for example if you end up with \[\frac{1}{x-2}\] then you have to exclude \(x=2\)

Answer 3

also if you start with \[\frac{x+4}{(x-2)(x+4)}\] and cancel, then you have to exclude both \(2\) and \(-4\)

Answer 4

\[\frac{ 6p-36 }{ 18}\]

That is one of my questions. I know it simplifies to p-6 over 3. How would I figure out the excluded value.

Answer 5

there are none since the denominator is a number

Answer 6

So if the equation is \[\frac{ 8b ^{5} }{ 64b^4 }\]
it would be simplified to \[\frac{ 1 }{ 8 }b\]
So they excluded would be b?

Answer 7

^ be careful. even though the simiplified version only has a number in the denominator, the original version excludes b = 0

Answer 8

Okay Thank you :)
