Answer:
-5x⁶ + 5x⁵ + 6x⁴ - 6x³
Step-by-step explanation:
Before we begin, remember that:
xᵃ * xᵇ = xᵃ⁺ᵇ
Now for the given question:
To answer this question, we will multiply each term from the first bracket by each term from the second bracket and then combine like terms to get the final expression.
This can be done as follows:
(6 - 5x²)(x⁴ - x³)
6(x⁴) + 6(-x³) - 5x²(x⁴) - 5x²(-x³)
6x⁴ - 6x³ - 5x⁶ + 5x⁵
Rearrange from largest power to smallest one, we will get:
-5x⁶ + 5x⁵ + 6x⁴ - 6x³
Hope this helps :)
