If `x+y=1` and `x^2+y^2=2` then `x^5+y^5=`

If |x+1|+y=5 and x-|y|=2, find x+y

If |x+2| + y=5 and x-|y|=1 , then the value of x+y is

If x ^(2) - 2x ^(2) y ^(2) + 5x + y-5 =0 and y (1) then y '' (1)=

If x - y = 2 and (2)/(x + y) = (1)/(5) then x = ……..

If (x_1,y_1) and (x_2,y_2) are the end points of a focal chord of the parabola y^2=5x , then 4x_1 x_2+y_1y_2=

If x^(2)y = 2x - y and |x| lt 1 , then (( y + (y^(3))/(3) + (y^(5))/(5) + ….oo))/((x + (x^(3))/(3) + (x^(5))/(5) + ……oo)) =

If x^(2)y = 2x - y and |x| lt 1 , then (( y + (y^(3))/(3) + (y^(5))/(5) + ….oo))/((x + (x^(3))/(3) + (x^(5))/(5) + ……oo)) =

Find (x+y)-:(x-y), if x=2/3, y=3/2 (ii) x=2/5, y=1/2 x=5/4, y=(-1)/3

If (x_(1), y_(1)) and (x_(2), y_(2)) are the end points of a focal chord of the parabola y^(2) = 5x , then 4x_(1)x_(2) + y_(1)y_(2) =
