Question

If the roots of 3x + 8x + 2 = 0 are a and 8, then (a '+ B) =?​

Answer 1

Step-by-step explanation:

Comparing 3x² + 8x + 2 = 0 with ax² + bx + c = 0:

a = 3, b = 8 and c = 2.

Hence (a + β) = - b / a

= – 8/3

and aβ = c / a

= 2/3.

Hence (a³+ β³)

= (a +β)³ - 3aβ (a + β)

= (-8/3)³ - 3 × 2/3 × (-8) / 3

= (-512/27) + (16 / 3)

= (-512 + 144) / 27

= - 368/27.... Answer
