Question

(3z-2)^3
how would i simplify this equation ​

Answer 1

Explanation:

Apply the binomial formula \((a-b)^{3}=a^{3}-3a^{2}b+3ab^{2}-b^{3}\)You can find the coefficient multipliers in row \(3\) of Pascal's triangle\((3z-2)^{3}\)\(27z^{3}-54z^{2}+36z-8\) so the Solution is \(27z^{3}-54z^{2}+36z-8\)
