el segundo 2, el cuarto 2, quinto 2, son de al cuadrado, los pequeñitos 2.
Porfavor agregar el paso a paso
2x² (5x + 2 + 3x²) - 5x (2 + x) - x² (6 + x) =
(10x³ + 10x² + 6x⁴) - (10x + 5x²) - (6x² + x³) =
10x³ + 4x² + 6x⁴ - 10x - 5x² - 6x² - x³ =
6x⁴ + 10x³ - x³ + 4x² - 5x² - 6x² - 10x =
6x⁴ + 9x³ - 7x² - 10x ← Expresión final
