MULTIPLYING POLYNOMIALS
(5k³) (8k⁴) (3k⁵)
= 40k⁷ (3k⁵)
= 120k¹²
====================================
(4x²) (-10x² + 5x)
= -40x⁴ + 20x³
====================================
(4m³ + 3) (4m³ + 3)
= 16m⁶ + 12m³ + 12m³ + 9
= 16m⁶ + 24m³ + 12m + 9
====================================
(3x + 4) (2x - 5)
= 6x² - 15x + 8x - 20
= 6x² - 7x - 20
====================================
- 5.) (y - 9) (y² + 2y + 1)
(y - 9) (y² + 2y + 1)
= y³ + 2y² + y - 9y² - 18y - 9
= y³ + 2y² - 9y² + y - 18y - 9
= y³ - 7y² - 17y - 9
