Question

Find the value of polynomial 5x-4x2+3 at
a) x = 0
b)x=2​

Answer 1

Answer:

$5(0) - 4 {(0)}^{2} + 3 \\ = 3 \\ 5(2) - 4 {(2)}^{2} + 3 = 10 - 16 + 3 = - 3$

Answer 2

Question:

Find the value of the polynomial 5x - 4x² + 3 at x = 0​

Answer:

a) 3

b) -3

Step-by-step explanation:

a) p(x) = 5x - 4x² + 3

   p(0) = 5(0) - 4(0)² + 3

           = 3

b) p(x) = 5x - 4x² + 3

   p(2) = 5(2) - 4(2)² + 3

          = 10 - 16 + 3

          = - 3
