Answer 1

Hey..plzz mark as brainliest.

Answer 2

5x²- 2√5x - 3
= 5x² - 3√5x +√5x - 3
= √5x(√5x - 3) + 1(√5x - 3)
= (√5x +1) (√5x-3)

if  √5x +1 = 0                       if √5x - 3 = 0
∴ x = -1/√5                                   x = 3/√5
∴ α = -1/√5                                   β = 3/√5

a = 5 
b = -2√5
c = -3

α+β = (-1/√5)+(3/√5)   
= 2/√5 ------(1)

-b/a = (2√5)/5
        = (2√5)/√5√5
        = 2/√5
        = α+β


α×β = (-1/√5)×(3/√5)
       = -3/5

c/a = -3/5
      = α×β


hence verified.
