If in two linear equations ax + by = c and dx + ey = f and a/d = b/e = c/f  then, which of the following is true about the two equations?

The ratio of roots of an equation

ax²+bx+b = 0 is p : q

Then find, √p/√q + √q/√p + √p/√q ?

I. 2p² + 5p + 2 = 0               II. 2q² + 11 q + 14 = 0

I. p² - 365 = 364

II. q - √ 529 = √ 169
