whats the question

OpenStudy (anonymous):

here is my question:

OpenStudy (anonymous):

Find the illegal value of c in the multiplication statement. \[\frac{ c^2-3c-10 }{ c^2+5c-14 }*\frac{ c^2-c-2 }{ c^2-2c-15 }\]

OpenStudy (er.mohd.amir):

factor all this

OpenStudy (er.mohd.amir):

thhen solve it

OpenStudy (anonymous):

i did just that, and the answers were not satisfactory

OpenStudy (anonymous):

? this is going to take a minute

OpenStudy (er.mohd.amir):

equal to what value is this.

OpenStudy (anonymous):

let me check my answer real quick

OpenStudy (anonymous):

nope I can't find the answer

OpenStudy (er.mohd.amir):

Q is not complete

OpenStudy (er.mohd.amir):

this is euqal to some thing oterwise how you get valve of C

OpenStudy (anonymous):

@Loser66

OpenStudy (anonymous):

the available answers are A. c=-7, c=-3 B. c= –7, c = –3, c = –2, and c = 5 C. c = 7, c = 3, c = –2, and c = –5 D. c = –7, c = –3, c = 2, and c = 5

OpenStudy (er.mohd.amir):

my ans are c=-7,-1,-3,-2

OpenStudy (anonymous):

Yes, that is my answer too, but it says that is wrong

OpenStudy (er.mohd.amir):

But it can not be ans

OpenStudy (anonymous):

Exactly

OpenStudy (er.mohd.amir):

since c=-7,-3 function become infinity

OpenStudy (loser66):

I am with @Er.Mohd.AMIR I got c = -7, -3

OpenStudy (anonymous):

Ok, yes that is one of the available answers, and is the one I was leaning to

OpenStudy (loser66):

Since -7, -3 make the expression undefined, hence they are "illegal answer" :)

OpenStudy (er.mohd.amir):

yes c=-7,-3 is illegel value i try to find legel value

OpenStudy (loser66):

That is just all of c but -7 and -3. that is it
