Question

A Find P(3), P15), P(6) of given polynomial P(x)=xpower3-xpower2+x+5.​

Answer 1

Step-by-step explanation:

a.

$p(3) = {3}^{3} - {3}^{2} + 3 + 5 \\ = 27 - 9 + 3 + 5 \\ = 26$

b.

$p(15) = {15}^{3} - {15}^{2} + 15 + 5 \\ = 3375 - 225 + 15 + 5 \\ = 3170$

c.

$p(6) = {6}^{3} - {6}^{2} + 6 + 5 \\ = 216 - 36 + 6 + 5 \\ = 191$
