Answer:
(b + 2)^2
Step-by-step explanation:
b^2 + 4b + 4
It's perfect square: a^2 + 2ab + b^2 = (a + b)^2
So
b^2 + 4b + 4 = (b + 2)^2
Answer:
Step-by-step explanation:
Note: When you divide exponents with the same constant, the exponent will be subtracted, and vice-versa, when you multiply exponents with the same constant, the exponents will be added.
