expand (n^2+6n-4)(2n-4)

expand

(n^{2} + 6 n - 4) (2 n - 4)

2 n^{3} + 8 n^{2} - 32 n + 16

Solution steps

(n^{2} + 6 n - 4) (2 n - 4)

Distribute parentheses

= n^{2} \cdot 2 n + n^{2} (- 4) + 6 n \cdot 2 n + 6 n (- 4) - 4 \cdot 2 n - 4 (- 4)

Simplify

n^{2} \cdot 2 n + n^{2} (- 4) + 6 n \cdot 2 n + 6 n (- 4) - 4 \cdot 2 n - 4 (- 4) : 2 n^{3} + 8 n^{2} - 32 n + 16

= 2 n^{3} + 8 n^{2} - 32 n + 16
