Answer:
To find the square of (4r + 2), we can use the formula (a + b)^2 = a^2 + 2ab + b^2.
Applying this formula, we have:
(4r + 2)^2 = (4r)^2 + 2(4r)(2) + 2^2
= 16r^2 + 16r + 4
Therefore, the square of (4r + 2) is 16r^2 + 16r + 4.
Step-by-step explanation:

Answer:
16r² +16r +4
Step-by-step explanation:
You want the simplified form of (4r +2)².
The distributive property can help you evaluate products of polynomials. It can be helpful to remember the form of a perfect square trinomial:
(a +b)² = (a +b)(a +b) = a(a +b) +b(a +b)
= a² +ab +ab +b²
= a² +2ab +b²
Here, we have a=4r and b=2. Then the square is ...
a² +2ab +b² = (4r)² +2(4r)(2) +(2)²
= 16r² +16r +4
