Question

Which of the following factored forms given below represent the correct factorization of the trinomial x^2 + 10x + 16

1. 2 (x + 4) (x + 2)

2. (2 + x ) ( 8 + x)

3. ( 4 + x ) ( 4 + x )

4. ( x - 2 ) ( x - 8 )

Answer 1

It would be 2 since that would give you the trio mail if expanded

Answer 2

2. (2 + x ) ( 8 + x)

Explanation:

x^2 + 10x + 16

Factor

What two numbers multiply to 16 and add to 10

8*2 = 16

8+2 = 10

(x+8)(x+2)
