Question

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

Answer 1

Answer:

answer is -10

Step-by-step explanation:

1. by substituting the value of x = -1, in the equation.
2. 6 × (-1)^3 - 3×(-1)^2 + 2(-1) +1.
3. = ( -6) -3 -2 +1
4. = -10

Answer 2

Step-by-step explanation:

factorial P(x) = 6x³ - 3x² + 2x + 1

denominator x = -1

Putting x = – 1 in the polynomial –

P(x) = 6x³ - 3x² +2x +1

P(–1) = 6(–1)³ – 3(–1)² + 2(–1) + 1

= 6(–1) – 3(1) – 2 + 1

= –6 – 3 – 1

= – 10
