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 option
I. 3x2-13x+12 =0
II. 2y2-15y+28=0
⇒ 3x2-9x-4x+12 = 0
⇒ 3x(x-3) - 4(x-3) =0
⇒ (x-3) (3x-4) =0
⇒ x= 4/3,3
⇒ 2y2-8y-7y+28=0
⇒ 2y(y-4)-7(y-4)=0
⇒ (y-4)(2y-7)=0
⇒ y=7/2,4
∴ x < y
I. 2x2+19x+45 = 0
II. 2y2+11y+12 = 0
