Given that x,y in R: solve (4x^(2)+3xy)+(2xy-3x^(2))iota=(4y^(2)-(x^(2))/(2))+(3xy-2y^(2))

x,y in R, solve :4x+3xy+(2xy-3x)i=4y-((x^(2))/(2))+(3xy-2y)i

Let x,y in R , then find the maximum and minimum values of expression (x^(2)+y^(2))/(x^(2)+xy+4y^(2)) .

Let x,y in R , then find the maximum and minimum values of expression (x^(2)+y^(2))/(x^(2)+xy+4y^(2)) .

Let x,y in R , then find the maximum and minimum values of expression (x^(2)+y^(2))/(x^(2)+xy+4y^(2)) .

Subtract: 13x^(2)-2y^(2)+5xy from 3x^(2)+4xy^(4)-8y^(2) hosizontally.

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

Solve the simultaneous equations : (6x+3y)/(xy) = 6, (2x+4y)/(xy) = 5
