Question

If P(x) = 5 x

2 - 4x + 5, evaluate P(1) + P(-1) + P(0).​

Answer 1

Step-by-step explanation:

4x + 5 + ( 4x – 5 ) + 0

4x + 5 - 4x - 5 + 0

So, 4x & 5 will be cutted and answer will be 0

Answer 2

Answer:

The value of P(1) + P(-1) +P(0) = 25

Step-by-step explanation:

The given polynomial is,

P(x) = 5x^2 -4x +5

Now we have to evaluate, P(1) +P(-1) +P(0)

So, P(1) = 5×(1) ^2-4×(1) +5 = 5-4+5 = 6

P(-1) = 5×(-1) ^2 -4×(-1) + 5 = 5 +4 +5 = 14

P(0) = 5×(0) ^2 -4×(0) +5 = 0-0+5 = 5

So, the value of,

P(1) +P(-1) +P(0) = 6+14+5 = 25
