Question

find the square. simplify your answer.
$(2s + 1)^2$

Explanation:

Step1: Apply square of sum formula

Recall the formula $(a+b)^2 = a^2 + 2ab + b^2$, where $a=2s$, $b=1$.

Step2: Calculate each term

$a^2 = (2s)^2 = 4s^2$, $2ab = 2*(2s)*1 = 4s$, $b^2 = 1^2 = 1$

Step3: Combine the terms

Add the calculated terms together.
$4s^2 + 4s + 1$

Answer:

$4s^2 + 4s + 1$
