Directions (next six 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. x2 +8x+15=0
II y2+3y+2=0
I. x2+8x+15=0
x2+5x+3x+15=0
x(x+5)+3(x+5)=0
(x+3)(x+5)=
⇒ x=-3,-5
II. y2+3y+2=0
y2+2y+y+2=0
y(y+2)+1(y+2)=0
(y+1)(y+2)=0
⇒ y=-1,-2
ஃ x
I. 4x2+19x+22=0
II. 2y2+11y+15=0
I. 2x2-9x+9=0
II y2-7y+12=0
I 4x2-8x+3=0
II 4y2-15y+14=0
I 3x2-13x+14=
II 2y2-5y+3=0
I 2x2 – 21x +52 = 0
II 2y2 – 11y+12=0
