Directions (Next Five Questions) : In the given questions , two equations numbered I and II are given. You have to solve both the equations and
I. 6x2+11x+4=0
II. 4y2-7y-2=0
6x2+8x+3x+4=0
2x(3x+4)+1(3x+4)=0
(2x+1)(3x+4)=0
x=-1/2, -4/3
4y2-8y+1 y-2=0
4y(y-2)+1(y-2)=0
(y-2)(4y+1)=0
y=2, -1/4
So, x
I. 2x2+11x+14=0
II. 2y2+15y+28=0
I. 9x2-45x+56=0
II. 4y2-17y+18=0
I. 4x2+16x+15=0
II. 2y2+3y+1=0
I. 2x2-7x+3=0
II. 2y2-7y+6=0
