Question

Evalúe cada polinomio para los valores dados:

a) 4x2 –x +3 ..................... x= -2

b) x2/3 –3x +5 .................. x=3/2

Answer 1

4x² - x + 3 x = -2

4(-2)² - (-2) + 3
4(4) + 2 + 3
16 + 5
= 21


(1/3)x² - 3x + 5 x = 3/2

(1/3)(3/2)² - 3(3/2) + 5
(1/3)(9/4) - (9/2) + 5
(3/4) - (9/2) + 5
= 5/4
