Directions (next five questions) : In these questions, two equations numbered I and II are given. You have to solve both the equations and mark the appropriate answer.
I. 3x2+17x+22=0
II. 5y2-21y+22=0
3x2+11x-6x+22=0
x(3x-11)2(3x-11)=0
(x-2)(3x-11)=0
x=2,11/3
5y2-11y-10y+22=0
y(5y-11)-2(5y-11)=0
(y-2)(5y-11)=0
∴ y = 2,11/5
Hence,
