I) 20x²-119x+176=0

II) 45y²+200y+155=0

x < y

x<=y

x>y

relationship between x and y cannot be determined

Explanation:

I) 20x²-119x+176=0
20x²-64x-55x+176=0
4x(5x-16)-11(5x-16)=0
(4x-11)(5x-16)=0
x=11/4,16/5
II)45y²+200y+155=0
45y²+45y+155y+155=0
45y(y+1)+155(y+1)=0
(45y+155)(y+1)=0
y=-155/45,-1
Hence, x > y
