I. x² – 13x + 36 = 0

II. 3y² – 29y + 18 = 0

I. 17x² - 26x – 16 = 0

II. 17y²- 26y + 9 = 0

'r' is one of the roots of equation (r - 1)p²Â - (5r + 2)p + 12 = 0 and sum of roots is (32/5), Determine the two roots of the equation.

I. 24x² - 58x + 23 = 0

II. 20y² + 24y – 65 = 0

I. 15/(√x)+9/(√x)=11√x

II. (√y)/4 + (5√y)/12 = 1/(√y)

I. x² - 4x – 21 = 0

II. y² + 12y + 20 = 0

I. 6x² + 23x + 10 = 0

II. 2y² - 3y - 5 = 0

I. 3x² - 14x + 15 = 0

II. 15y²- 34 y + 15 = 0

In each of these questions, two equations (I) and (II) are given.You have to solve both the equations and give answer   

I: 3x² - 18x + 24 = 0

II: 5y² + 10y - 15 = 0
