Answer 1

Answer:

215 27

Step-by-step explanation:

Solution

Given, a and 3 are zeroes of 3x² - 5x - 2 = f(x)

on comparing f(x) with ax² +bx+c

We get, a = 3, b=-5, c= -2

a+β=

-b

a

α.β. C - a -2 3

a³ + 3³ = (a +ß)³ - 3aß(a + 3)

5 3 => - ³ (7²) (3) - 3 3

125 10 || + 27 3

125 +90 27

a³ + 3³ 3 215 27

-(-5)
