Question

Factor the following polynomial: x2 + 16x + 48
(x + 6)(x + 8)
(x + 16)(x + 1)
(x + 4)(x + 12)
(x + 8)(x + 2)

Answer 1

first one :)

Answer 2

x^2 + 16x + 48
= x^2 + 4x +12x + 48
= x(x+4) + 12(x+4)
= (x+12)(x+4)

Answer 3

The first one is NOT correct. Try to expand it.
(x + 6)(x + 8)
= x(x + 8) + 6(x + 8)
= x^2 + 8x + 6x + 48
= x^2 + 14x + 48
