Question

sea P(×)=2×3+8×2+2×-12. calcula el valor numérico de P(×) para : A) x=1 B) x=3 C)x=3

Answer 1

P(1)= 2(1) 3+8(1) 2+2(1)-12= 12 P(2)= 2(2) 3+8(2) 2+2(2)-12=48 P(3)= 2(3) 3+8(3) 2+2(3)-12=78

Answer 2

P(1)= 2(1) 3+8(1) 2+2(1)-12= 12 P(2)= 2(2) 3+8(2) 2+2(2)-12=48 P(3)= 2(3) 3+8(3) 2+2(3)-12=78
