Its not a correct factorization

Munchkin · Answer 2

Step-by-step explanation:

(x+3) (x-5)

= x²-5x+3x-15 = x²-2x-15

But the given polynomial x³-15

So it is not the correct factorization.

Again, (x-3) (x+5)

= x²+2x-15

But the given polynomial x³-15

So it is not the correct factorization.

Again, (x+3) (x²-4x+5)

= x³-4x²+5x+3x²-12x+15

= x³-x²-7x+15

But the given polynomial x³-15

So it is not the correct factorization.

So, optionD is the correct answer
