Answer 1

Answer:

C. (x + 8) (x + 7)

Step-by-step explanation:

To factor this trinomial, you must split the middle term (15x) into two terms that can be added to get 15x, and multiplied to get 56:

$x^2 + 15x + 56$

$x^2 + 7x + 8x + 56$

Group:

$(x^2 + 7x) (8x + 56)$

Take out the GCF (Greatest Common Factor):

x(x + 7)  8(x + 7)

(x + 8) (x + 7)
