Question

Sendo P(x)=X^4+3X^2-X+1, calcular A)P(2) B)P(-2)

Answer 1

P(x)=X⁴+3X²-X+1



calcule


A)P(2)
P(x)=X⁴+3X²-X+1
P(2)=2⁴+3.2²-2+1
P(2)=16 + 3.4 - 2 + 1
P(2)=16 + 12 - 2 + 1
P(2)=28 - 1
P(2)=27





B)P(-2)
P(x)=X⁴+3X²-X+1
P(-2)=(-2)⁴+3.(-2)²-(-2)+1
P(-2)=16 + 3.4 + 2 + 1
P(-2)= 16 + 12 + 3
P(-2)= 31
