1.

I. 10x^(2) + 33x + 27 = 0""II. 5y^(2) + 19y+18 = 0

Answer»

` x gt y`
` x GE y`
` x lt y`
Relationship between x and y cannot be determined

SOLUTION :I. ` 10x^(2) + 33x+27 = 0`
`x_(1) =(-33+sqrt(b^(2)-4AC))/(2a)=(-33+sqrt(1089-4xx10xx27))/20=(-33+3)/20`
` x_(2)=(-33-sqrt(b^(2)-4ac))/(2a)`
` x_(2) = (-33-sqrt(1089-1080))/20`
` x_(1) = (-33+3)/20,x_(2)= (-33-3)/20`
` x_(1) = (-30)/20, x_(2) = (-36)/20 = (-9)/5, x = (-3)/2, (-9)/5`
II. ` 5y^(2) + 19y+18 = 0`
` y_(1) = (-19-sqrt(361-4xx18xx5))/10`
` y_(2) = (-19-sqrt(361-360))/10`
` y_(1) = (-19+1)/10`
` y_(2) = (-19-1)/10 = (-18)/10 = (-9)/5 = (-20)/10 = - 2`
` y= (-9)/5, -2 rArrx ge y`
