How do you multiply `-8x ^ { 5} ( - 4x ^ { 4} - 3x ^ { 2} - 1)`?

Answer 1

`32x^9 +24x^7 +8x^5`

Explanation:

Multiply using the distributive law whereby the factor in front of the bracket is multiplied by each term inside the bracket.

`-8x^5(color(blue)(-4x^4)color(lime)(-3x^2)color(red)(-1))`

`=color(blue)(+32x^9)color(lime)(+24x^7)color(red)(+8x^5)`
