Question

Which expression is equivalent to (2g3+4)2?

Answer 1

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$g^{6}$ + 8g³ + 8g³ + 16 ← collect like terms

=4$g^{6}$ + 16g³ + 16 → B
