Answer:
x+2
Step-by-step explanation:
A factor of a polynomial can be thought of as the value of x at which the polynomial is equal to zero.
So, you can use the values in the options given and put them in the polynomial from the question.
for example: try, part a) x-1, here x=1 since the factor is x-1=0
put this value in the polynomial to see if it results to zero.
so this isn't the answer.
now try, part d) x + 2, here, x = -2
you'll see this is the factor!
