Answer:
2(b + 3c)²(b + 3c)² is equivalent to
2b^4 + 8b³c + 12b²c² + 8b²c³ + 2c^4
Step-by-step explanation:
The expression
2(b + 3c)²(b + 3c)²
Is equivalent to the expression
2(b + 3c)^4
This can be further expanded using the Pascals triangle as
2(b^4 + 4b³c + 6b²c² + 4b²c³ + c^4)
= 2b^4 + 8b³c + 12b²c² + 8b²c³ + 2c^4
