3 roots x= -1, +5, -8
OpenStudy (witty_roger):
hence factors are x+1, x-5 and x-8
OpenStudy (anonymous):
it gives me a box to write it not a multiple choice
OpenStudy (witty_roger):
wat descending order does it mean by?

does this one give me three aswell or only two because the x gives me 2 but idk about the y axis
OpenStudy (witty_roger):
u shud see x axis only...
OpenStudy (anonymous):
okay only x then
OpenStudy (witty_roger):
never see y axis for roots...
OpenStudy (anonymous):
so it would be x+1 and x+7?

OpenStudy (witty_roger):
nope...x-1 and x-7
OpenStudy (anonymous):
so its minus
OpenStudy (anonymous):
i got my signs wrong
OpenStudy (witty_roger):
no roots are positive only
OpenStudy (witty_roger):
see d theory is if u have a factor...u have to equate it to zero...in order to get ur root

OpenStudy (witty_roger):
so if ur factor is x-7 then ur root is x=7
OpenStudy (witty_roger):
x= +7 (Positive root,, negative sign sign in factor)
and vice versa
OpenStudy (anonymous):
oh okay then now i get my signs
