whats is the simplified form of 4z^2+16+15/2z^2-z-16
factor out what you can on both the top and bottom
Which in this case is not much,....
try to factore the bottom trinomial
from the 16 you have missed a z ,yes ?
Hmm that might make more sense :P
Oh I missed that. yes there is a z after 16
ok than do you know how you solve a quadratic equation ?
the formula of discriminant ?
use decomposition factoring on top
so than do it without
Okay thank you.:) I'm just not very good at factoring so I wasn't sure how.
Do you have an idea about the factoring on top?
ill give you a hand
do u still need help?
Yes, I thought I got it but I didn't... so yes please
ok jsut give a few minutes
4z^2+16+15/2z^2-z-16 just as Bitmaximus had stated earlier factor both expressions then it will be simplified
factor 4z^2 + 16 z + 15 (2z+3)(2z +5) then factor the bottom trinomial 2z^2 - z - 16
do u see what i am doing?
Yeah I'm following so far
so try and factor 2z^2 - z - 16
wouldn't my answer be 2z+3 over z-3
u mean for the final answer
yes my simplified answer
ok let me check first
the simpllified form is (2z+3) ( 2z+5) / 2z^2-z-16
even though it is not the same as ur answer, but the problem is that u can not factor the bottom trinomial
are u still with me?
Yeah I tried to factor the bottom it doesn't make that much sense
that is why i think that ^^ is the simplified form
Well your answer makes sense.. Thank you:)
