If `x ,y in R` and `2x^2+6xy+5y^2=1`,then `|x|lt=sqrt(5)` b. `|x|geqsqrt(5)` c. `y^2lt=2` d. `y^2lt=4`

x + y lt 5

If (4x^2-3y^2):(2x^2+5y^2)=12:19 then x:y=

Add the following 5y^2x^2, -6xy, 8x^2y^2, 3xy

2x - y gt 1 , x - 2y lt 1

If x:y::5:2, then (x ^(2) +y)/(x + y ^(2)) =?

If 2x+3y=5 and 3x+2y=10 then x-y= (a) 3 (b) 4 (c) 5 (d) 6

If x:y=5:6, then (3x^2 - 2y^2) : (y^2 - x^2) is

Add : 4x^(2)y, - 3xy^(2), -5xy^(2), 5x^(2)y

If x,y in R satisfy the equation x^(2)+y^(2)-4x-2y+5=0, then the value of the expression ((sqrt(x)-sqrt(y))^(2)+4sqrt(xy))/((x+sqrt(xy))) is
