Answer:
4x³ - 110x² + 750x
Step-by-step explanation:
(30 - 2x)(25 - 2x) × x
(x × 30 - x × 2x)(25 - 2x)
(30x - x × 2x)(25 - 2x)
(30x - 2x²)(25 - 2x)
30x(25 - 2x) - 2x²(25 - 2x)
30x × 25 - 30x × 2x - 2x²(25 - 2x)
30x × 25 - 30x × 2x - 2x² × 25 + 2x² × 2x
750x - 30x × 2x - 2x² × 25 + 2x² × 2x
750x - 60x × 2x - 2x² × 25 + 2x² × 2x
750x - 60x² - 50x² + 2x² × 2x
750x - 60x² - 50x² + 4x³
750x + (- 60x² - 50x²) + 4x³
750x + (- 60 - 50)x² + 4x³
750x - 110x² + 4x³
= 4x³ - 110x² + 750x

Answer:
4x³ - 110x² + 750x
Step-by-step explanation:
(30 - 2x)(25 - 2x) × x
(x × 30 - x × 2x)(25 - 2x)
(30x - x × 2x)(25 - 2x)
(30x - 2x²)(25 - 2x)
30x(25 - 2x) - 2x²(25 - 2x)
30x × 25 - 30x × 2x - 2x²(25 - 2x)
30x × 25 - 30x × 2x - 2x² × 25 + 2x² × 2x
750x - 30x × 2x - 2x² × 25 + 2x² × 2x
750x - 60x × 2x - 2x² × 25 + 2x² × 2x
750x - 60x² - 50x² + 2x² × 2x
750x - 60x² - 50x² + 4x³
750x + (- 60x² - 50x²) + 4x³
750x + (- 60 - 50)x² + 4x³
750x - 110x² + 4x³
= 4x³ - 110x² + 750x
