you can never divide by 0
so where will there be a problem with this one?
it's A- (3)
ik how did u get tht?
he is wrong, by the way
okay so then wat is it philip
you cannot divide by zero, so what values for x will cause problems here?
that is the question
what is the denominator? and when is it 0?
sorry, forgot to ask, do you want to learn this stuff or just want to fill in some homework? I am ok with it either way.
Factorize them (x^2-16)/(x^2-6x+9)
(x^2-16) = (x-4)(x+4)
since any denominator makes the whole equation undefined
Therefore the no. 3 is Refused
i mean Answer (A)
fill in sum homework but kind of want to know a little about it.
i mean when the denominator=0
the whole equation is undefined
yep, that's right. I was mistaken.
appologies where appropriate
