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

If (5x - 3y) : (2x + 4y) = 11 : 12 , then find x : y .

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

If (5x+2y) : (10x+3y) = 5:9 , then (2x^2+3y^2 ):(4x^2+9y^2) =? यदि (5x+2y) : (10x+3y) = 5:9 , है, तो (2x^2+3y^2 ): (4x^2+9y^2) =?

If x^(2) + 3y^(2) + 4z^(2)+ 19 = 4 sqrt(3) ( x + y + z) , then the value of ( x - y + 4z) is:

If 4x^(2)+y^(2)=1 then the maximum value of 12x^(2)-3y^(2)+16xy is

Identify the type of conic section for each of the equations 1. 2x^(2) -y^(2) = 7 2. 3x^(2) +3 y^(2) -4x + 3y + 10 =0 3. 3x^(2) + 2y^(2) = 14 4. x^(2) + y^(2) + x-y=0 5. 11x^(2) -25y^(2) -44x + 50y - 256 =0 6. y^(2) + 4x + 3y + 4=0

Solve for (x - 1)^(2) and (y + 3)^(2) , 2x^(2) - 5y^(2) - x - 27y - 26 = 3(x + y + 5) and 4x^(2) - 3y^(2) - 2xy + 2x - 32y - 16 = (x - y + 4)^(2) .
