Question

Даны многочлены pı(a) = - 4 - За и р2(a)= 7-8а. Найдите:
=) p(a) = pı(a) + P2(a)
=) p(a) = pı(a) - P2(a) помогите пж

Answer 1

1. p(a) = p₁(a) + p₂(a) = -4 - 3a + 7 - 8a = 3 - 11a

2. p(a) = p₁(a) - p₂(a) = -4 - 3a - 7 + 8a = -11 + 5a

Answer 2

Ответ:

Объяснение:

p1(a) = - 4 - За и р2(a) = 7 - 8а.

1) p(a) = p1(a) + p2(a) = - 4 - 3a + 7 - 8a = 3 - 11a

2) p(a) = p1(a) - p2(a) = - 4 - 3a - 7 + 8a = 5a - 11
