I12x^(2) - x -1 = 0 ""II. 20y^(2) - 41y+20 = 0

Answer»

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

SOLUTION :I. ` 12x^(2) - x - 1 = 0`
`x_(1) =(-b+sqrtD)/(2a) =(1+sqrt(1-4 xx12xx-1))/24`
` =(1+7)/24 = 8/24 = 1/3`
` x_(2) = (-b-sqrtD)/(2a) `
` x_(2) = (1-7)/24 = (-6)/24 = (-1)/4`
` x = 1/3, -1/4`
II` 20y^(2)-41y+20=0`
` y_(1) = (41-sqrt(1681-1600))/40`
` y_(2) = (41-sqrt(1681-1600))/40`
` y_(1) = (41+9)/40 = 50/40,y_(2) = 32/40`
` y = 5/4,4/5 RARRX lt y`
