-3n²+4n es igual a -n×(3n-4)
= (-3y²) (-7y²) + (-3y²) – 5y + (-3y² ) – 2 + (-5y) – (-7y²) + (-5y) – 5y + 2 + (-2) (-7y²) + (-2) – 5y + (-2) – 2
(-a) (-b)=ab, + (-a)= -a
= 3 – 7y² y² - 3 – 5y²y – 3 – 2y² + 5 – 7y²y- 5 5yy- 5- 2y+2-7y² - 2- 5y + (-2)– 2

Respuesta:
expandir (-3y² - 5y - 2) (-7y² + 5y + 2 ) : 21y⁴ + 20y³ - 17y² - 20y – 4
* pasos
(-3y² - 5y – 2) (-7y² + 5y + 2)
*Aplicar la siguiente regla de los productos notables
= (-3y²) (-7y²) + (-3y²) – 5y + (-3y² ) – 2 + (-5y) – (-7y²) + (-5y) – 5y + 2 + (-2) (-7y²) + (-2) – 5y + (-2) – 2
*Aplicar la regla de los signos
(-a) (-b)=ab, + (-a)= -a
= 3 – 7y² y² - 3 – 5y²y – 3 – 2y² + 5 – 7y²y- 5 5yy- 5- 2y+2-7y² - 2- 5y + (-2)– 2
*Simplificar
3 – 7y² y² - 3 – 5y²y – 3 – 2y² + 5 – 7y²y- 5 5yy- 5- 2y+2-7y² - 2- 5y + (-2) – 2: 21⁴ y 20³ - 17y² - 20y – 4
= 21y⁴ + 20y ³ - 17² - 20y – 4
