Question

find the value of P(1) + P(-1) for the polynomial P(x)= x3 - 2x-25x +3.​

Answer 1

Answer:

p(x) = x³-2x²-25x+3

p(1) = 1³-2*1²-25*1+3

=> 1 - 2 - 25 + 3

=> -24

p(-1) = (-1)³-2(-1)²-25(-1)+3

=> -1 - 2 + 25 + 3

=> 25

p(1) + p(-1)

=> -24 + 25

=> 1

Answer 2

Answer:0

Step-by-step explanation:

p(2) =(2)3   -3(2)+2(2)

=8-12+4=0
