Answer:

Excluded Value :  3 and  -5  

Step-by-step explanation:

hello :

Excluded Value :    and    

the excluded value when : x²+2x-15=0

( x²+2x+1)-1-15=0

means : (x+1)²-16=0       (x+1)²-4² = 0

by identity : a²-b² =(a-b)(a+b)

(x+1-4)(x+1+4) =0   so :      (x-3)(x+5) =0  means : x-3=0 or x+5=0

x=3 or x= -5

Excluded Value :  3 and -5
