Answer:
x³ + 3x² + 3x + 2
Step-by-step explanation:
Given
(x + 2)(x² + x + 1)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x² + x + 1) + 2(x² + x + 1) ← distribute both parenthesis
= x³ + x² + x + 2x² + 2x + 2 ← collect like terms
= x³ + 3x² + 3x + 2
Answer:
x³+3x²+3x+2

Answer:
19th term = ar^18
19th term = 774,840,978
Step-by-step explanation:
First term, a = 2
Common ratio, r = 3
nth term of a geometric sequence = ar^(n-1)
19th term = ar^(19-1)
19th term = ar^18
= 2 × 3^18
= 2 × 387,420,489
= 774,840,978
19th term = 774,840,978
