Which is a factor of the trinomial x² - 2x - 15?
A.) (x – 13)
B.) (x + 13)
C.) (x - 5)
D.) (x + 5)

(x-5)

Step-by-step explanation:

Factorizing x^2-2x-15:

=== x^2-5x+3x-15

  =  x(x-5)+3(x-5)

  =  (x+3)(x-5)

The factors of  x^2 - 2x - 15 are (x+3)(x-5)

the perimeter is increased by a factor of 2
