Answer:

(n + 7)(n + 2) = 0

Step-by-step explanation:

Set the equation equal to 0. Add 14 to both sides:

n² + 9n = -14

n² + 9n (+14) = -14 (+14)

n² + 9n + 14 = 0

Find factors of 14 & n, that, when combined, will equal 9n.

n² + 9n + 14 = 0

n 7

n 2

(n + 7)(n + 2) = 0

(n + 7)(n + 2) = 0 is your answer.

Evaluate the function f(x) = 2x3 - 6x + 1 for f(-2).

erma4kov [3.2K]

Answer:

- 3

Step-by-step explanation:

$f(x) = 2 {x}^{3} - 6x + 1 \\ plugging \: x = - 2 \\ f( - 2) = 2( { - 2})^{3} - 6( - 2)+ 1 \\ = 2 \times ( - 8) + 12 + 1 \\ = - 16 + 13 \\ = - 3 \\ f( - 2) = - 3$
