Downy mildew or Green ear disease of Sorghum is

if x satisfies 3x² – 5x – 12 = 0, find the sum of reciprocals of roots.

I. 6x² + 37x + 45 = 0

II. 3y² - 11y + 6 = 0

Equation 1: x² - 90x + 2025 = 0

Equation 2: y² - 88y + 1936 = 0

The roots of the equations x² + 16x + 63 = 0

I.√(3x-17)+ x=15

II.  y+  135/y=24 

I. 3y² + 16y + 16 = 0

II. 2x² + 19x + 45 = 0

I. 6x² - 23x + 7 = 0

II. 6y² - 29y + 9 = 0

(i) 2x² – 9x + 10 = 0

(ii) 4y² – 12y + 9 = 0

I.  p²= ∛1331

II. 2q²  - 21q + 55 = 0

I. 12x² + 22x + 8 = 0

II. 4y² - y − 3 = 0
