Answer:

$p( - 2) = \\ \\ \\ p(x) = 5x - 4 {x}^{2} + 3 \\ \\ \\ p( - 2) = 5 \times (- 2) - 4( { - 2}^{2} ) + 3 \\ \\ \\ = > - 10 - 16 + 3 = - 23$

Answer 2

Answer:

Step-by-step explanation:

p(x) = -2

p(x) = 5x - 4x² + 3

      = 5 * (-2) - 4 * (-2)² + 3

      = -10 - 4 * 4 + 3

      = -7 - 16

      = - 23
