28/(x^2-9)+x/(3-x)+7/(3+x)=1

x=-2, or x=4

Step-by-step explanation:

Hello,

So, assuming that we take x different from 3 and -3 (as dividing by 0 is not allowed)

The sum of the zeroes is 2=4-2 and the product is -8=4*(-2), so we can conclude.

Thanks

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
