For this case, we must show the first step to simplify the following expression:
[tex]\frac {3 (x + 8) ^ 2} {(x + 2)}[/tex]
So, the first step is to solve the binomial to the square of the numerator, in the form:
[tex](a + b) ^ 2 = a ^ 2 + 2ab + b ^ 2[/tex]
So, we have:
[tex](x + 8) ^ 2 = x ^ 2 + 2 * x * 8 + 8 ^ 2\\(x + 8) ^ 2 = x ^ 2 + 16x + 64[/tex]
Then, the expression is as follows:
[tex]\frac {3 (x ^ 2 + 16x + 64)} {(x + 2)}[/tex]
Answer:
Option D
