Question

Find P(-1) and P(1) in the polynomial: P(x)= 2x³+5x²-7x-13​

Answer 1

HOPE THIS ANSWER HELPS YOU

Step-by-step explanation:

P(-1) = 2(-1)³ + 5(-1)² - 7(-1) - 13

= 2(-1) + 5(1) + 7 - 13

= -2 + 5 + 7 - 13

= -15 + 12

= -3

P (1) = 2(1)³ + 5(1)² - 7(1) - 13

= 2 + 5 - 7 - 13

= 7 - 20

= -13

Answer 2

Answer:

=2(-1)^3+5(-1)^2-7(-1)-13

=-2+5+7-13

=-3

P(1)

=2(1)^3+5(1)^2-7(1)-13

=2+5-7-13

=–13
