CPM Homework Help : PC3 Problem 13-95

Solve: $\left(3a−2\right)^4+\left(6a+1\right)^3=$ $81a^4+17$

Hint:

Use the Binomial Theorem or Pascal's triangle to expand the terms on the left side of the equation.

Step:

$81a^{4} − 216a^{3} + 216a^{2} − 96a + 16 + 216a^{3} + 108a^{2} + 18a + 1 = 81a^{4} + 17$
