1)8b(3b^4-3b+1)=24b^5-24b^2+8b
2)(2c+1)(c+4)=2c^2+8c+c+4=2c^2+9c+4
3)(3a+b)(8a-2b)=24a^2-6ab+8ab-2b^2=24a^2-2ab-2b^2
4)(1+a)(a^2+3a-8)= a^2+3a-8+a^3+3a^2-8a
Ответ:
1) 24b^5 - 24b^2 + 8b
2) 2c^2 + 9c + 4
3) 24a^2 + 2ab - 2b^2
4) 4a^2 - 5a - 8 + a^3
Объяснение:
===========================
1) 8b(3b^4 - 3b + 1) = 24b^5 - 24b^2 + 8b
2) (2c + 1)(c + 4) = 2c^2 + 8c + c + 4 = 2c^2 + 9c + 4
3) (3a + b)(8a - b) = 24a^2 - 6ab + 8ab - 2b^2 = 24a^2 + 2ab - 2b^2
4) (1 + a)(a^2 + 3a - 8) = a^2 + 3a - 8 + a^3 + 3a^2 - 8a = 4a^2 - 5a - 8 + a^3
