Question

when x= -1, what is the
value ol the polyonimal 2x³+ 2x
​

Answer 1

Solution:

Given:

x = -1

We have to find:

2x³ + 2x

P(x) = 2x³ + 2x

At x = -1,

P(-1) = 2(-1)³ + 2(-1)

= 2(-1) + (-2)

= -2 -2

= -4

Thus, value = -4

Answer 2

Answer:

Step-by-step explanation:

• SINCE x= -1 ,

• SO, 2x³+ 2x=

1. 2* (-1)³ + 2* (-1)
2. 2*(-1) + (-2)
3. -2-2
4. SO, -4 IS THE ANSWER
