Question

1. Simplify:
points)
(2x - 3x2 + 4x3 – 6x5) + (7x6 – 5x3 + 3x²)

Answer 1

7x⁶ - 6x⁵ - x³ + 2x

Explanation:

Step 1: Write expression

(2x - 3x² + 4x³ - 6x⁵) + (7x⁶ - 5x³ + 3x²)

Step 2: Combine like terms (x³)

7x⁶ - 6x⁵ - x³ - 3x² + 2x + 3x²

Step 3: Combine like terms (x²)

7x⁶ - 6x⁵ - x³ + 2x
