Answer:
(x + 2)(x + 3)
Explanation:
To factor perfect square trinomials, we have to follow a certain trick, the two factor numbers must equal b (in this case 5x) when added and equal c (in this case 6) when multiplied.
Simply enough, two numbers that do this is 2 and 3.
Therefore, our factor numbers are 2 and 3, making the last eqaution (x + 2)(x + 3)
