Question

Find the value of the polynomial P(x) = 6x³ - 3x² +2x +1 if x = -1

10

-10

0

-1​

Answer 1

Answer:

The answer is -10 .

Second option is the correct answer.

Step-by-step explanation:

P(x)

$= 6 {x}^{3} - 3 {x}^{2} + 2x + 1$

When x = -1 , P(-1) $= 6( { - 1})^{3} - 3( { - 1})^{2} + 2( - 1) + 1 \\ = 6( - 1) - 3(1) + (- 2) + 1 \\ = - 6 - 3 - 2 + 1 \\ = - 11 + 1 \\ = - 10$
