" 4."7(x-2y)^(2)-25(x-2y)+12

Factorize the following expressions 7(x-2y)^2-25(x-2y)-12

Factorize : 7(x-2y)^2 - 25 (x-2y)+12

If a parabola is represented by 25(x^(2)+y^(2))=(4x-3y-12)^(2), then

Find the product: (3x-5y-4)(9x^(2)+25y^(2)+15xy+12x-20y+16)

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

Solve:(1)/(2(2x+3y))+(12)/(7(3x-2y))=(1)/(2)(7)/(2x+3y)+(4)/(3x-2y)=2 where 2x+3y!=0 and 3x-2y!=0

Let (x,y) satisfying x^(2)+y^(2)-4x+4y-12=0 Now if A=Max(x^(2)+y^(2)-6x+8y+25)&B=Max(x^(2)+y^(2)+24x-10y+169) Calculate 2A+3B

If x=7 tonches the circle x^(2)+y^(2)-4 x-6 y-12=0 then the point of contact is

Find the product. (3x-5y-4)(9x^2+25y^2+15xy-20y+12x+16)
