Taffy · Answer 1

Let f (x) = x^5 - 2x^2 + x + c

For the denominator to divide numerator, then

f (-2) = 0

(-2) ^5 - 2 (-2) ^2 - 2 + c = 0

-32 - 2 (4) - 2 + c = 0

-32 - 8 - 2 + c = 0

-42 + c = 0

c = 42.

The constant c = 42.

Sebastian Lutz · Answer 2

If f (x) = x^5 - 2 x^2 + x + c is divisible by : x + 2

then : f ( - 2) = 0

f ( - 2) = ( - 2) ^5 - 2 ( - 2) ^2 + ( - 2) + c = 0

- 32 - 8 - 2 + c = 0

c = 32 + 8 + 2

Answer:

c = 42
