Answer:

Step-by-step explanation:

2x³ - 5x² - 14x + 8

Simple method

Sum of Zeroes = - (-5)/2 = 5/2

factorization methos

2x³ - 5x² - 14x + 8

= (x + 2)(2x² - 9x + 4)

= (x + 2)(2x² - 8x - x + 4)

= (x + 2)(2x(x - 4) - 1(x - 4))

= ( x + 2)(2x - 1)(x - 4)

x = -2 , 1/2 , 4

Sum of Zeroes = -2 + 1/2 + 4

= 5/2
