Question

Find value of the polynomial p(x) = 5x +3-4x? at x =2.​

Answer 1

$p(x) = 5x + 3 - 4x^2$

$p(2) = 5(2) + 3 - 4(2)^2 \\ p(2) = 10 + 3 - 16 \\ p(2) = -3$

Answer 2

Answer

-3

Step-by-step explanation:

p(x) = 5x + 3 - 4x²

put value of x = 2

now it is quite simple

p(2) = 5(2) + 3 - 4(2)²

p(2) = 10 + 3 - 4(4)

p(2) = 13 - 16

p(2) = -3
