Answer:
B
Step-by-step explanation:
(2g³ + 4)² = (2g³ + 4)(2g³ + 4)
Each term in the second factor is multiplied by each term in the first factor, that is
2g³(2g³ + 4) + 4(2g³ + 4) ← distribute both parenthesis
= 4 + 8g³ + 8g³ + 16 ← collect like terms
=4 + 16g³ + 16 → B
If an expression is the difference of two squares, it will follow this format:
where a and b are integers or variables.
1)
Since the expression follows the format, it's a DoTS.
2) Since the binomial has an addition sign, it isn't a DoTS.
3)
The second term isn't an integer, so the expression isn't a DoTS.
4)
Since the expression follows the format, it's a DoTS.
Therefore, the first and fourth expressions are differences of two squares.
