Answer: C
Step-by-step explanation:
To factor a trinomial, you need to multiply 'a' and 'c' and see what two number add to equal 'b' but also multiply to equal the product of 'a' and 'c'.
So, what two numbers multiply to equal 16 but simultaneously add to equal 8?
That is +4 and +4. Instead of writing (x+4)(x+4), you can write (x+4)^2, or answer C.
