Question

Помогите решить
Разложение на множители:
9к^12-30k^6t^5+25t^10
3m^9y+18m3y^5+27y^9
d+2cd+c^2d
-1-121a^2b^2+22ab

Answer 1

9k¹² - 30k⁶t⁵ + 25t¹⁰= (3k⁶ - 5t⁵)² = (3k⁶ - 5t⁵)(3k⁶ - 5t⁵)

3m⁹y+18m³y⁵+27y⁹ = 3y(m⁹ + 6m³y⁴ + 9y⁸) 

d+2cd+c²d = d(1+2c+c²) = d(1+c)(1+c)

-1-121a²b²+22ab = -(11ab - 1)² = -(11ab - 1)(11ab - 1)

Удачи!
