`y^(2)=12x`

Factorize: 4(x-y)^(2)-12(x-y)(x+y)+9(x+y)^(2)

One of the points on the parabola y^(2) = 12 x with focal distance 12, is

The points on the parabola y ^(2) =12 x whose focal distance is 4, are

Factorise : (x-2y)^(2) - 12(x-2y) + 32

The equation of the circle which, passes through the point (-2, -3) and has its centre on the negative direction of x-axis and is of radius 5 units is (i) x^(2) + y^(2) + 12 x + 11 = 0 (ii) x^(2) + y^(2) - 12 x + 11 = 0 (iii) x^(2) + y^(2) - 12 x - 11 = 0 (iv) x^(2) + y^(2) + 12 x - 11 = 0

Factorize: 4(x-y)^2-12(x-y)(x+y)+9(x+y)^2

If the line x + y = k is a normal to the curve y2 = 12x, find the value of k.

x+2y=-1,2x-3y=12
