Question

Find p(-2), for the given polynomial p(x) = x³- 3x²- 12x+ 5.please tell me fasttttttt

Answer 1

Answer:

9

Step-by-step explanation:

p(-2) = (-2)³- 3(-2)²- 12(-2)+ 5

        = -8 -3(4) + 24 + 5

        = -8 - 12 + 24 + 5

        = -20 + 24 + 5

        = 4 + 5

        = 9

Answer 2

Answer:

$Given, p(-2)$

$p(x) = x^3- 3x^2- 12x+ 5$

$p(-2) = (-2)^3- 3(-2)^2- 12(-2)+ 5$

$p(-2) = -8-12+24+5$

          $=9$
