Solution

The correct option is E Relationship between x and y cannot be established.
Equation I
3x2+29x+56=0
3x3+21x+8x+56=0
3x(x+7)+8(x+7)=0
(3x+8)(x+7)=0
x=7,x=83
Equation II
2y2+15y+25=0
2y2+10y+5y+25=0
2y(y+5)+5(y+5)=0
(y+5)(2y+5)=0
y=5,y=52
Hence, relationship between x and y cannot be established
