A(n) = 2 + 9(n - 1) = 2 + 9n - 9
A(n + 1) = 2 + 9(n + 1 - 1) = 2 + 9n = (2 + 9n - 9) + 9 = A(n) + 9
Therefore, the recursive formular is A(n) = A(n - 1) + 9
Answer:
x = -5 + 
Step-by-step explanation:
f(x) = x² + 10x - 1
x² + 10x = 1
x² + 10x + 25 = 1 + 25
(x + 5)² = 26
take the square root of each side to get:
x + 5 = √26
x = √26 - 5 or -5 + √26
