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

It will take 20 months for the cost to be same.

Step-by-step explanation:

Apartment A;

Security deposit = $1000

Each month cost = $1200

Let,

x be the number of months.

A(x) = 1000 + 1200x

Apartment B;

Security deposit = $1500

Each month cost = $1175

B(x) = 1500 + 1175x

The cost will be same when the functions are equal, therefore,

A(x) = B(x)

1000+1200x=1500+1175x\\1200x-1175x=1500-1000\\25x=500

Dividing both sides by 25

\frac{25x}{25}=\frac{500}{25}\\x=20

It will take 20 months for the cost to be same.
