Fill in the blanks:
`2x^2y+3x(4y)-2y(12x)+8=2x^2y-`______+8

find x and y : 2x+y-5=0 3x+2y-8=0

Simplify: (2x+3y)(3x+4y)-(7x+3y)(x+2y)

Add 4x^2y ,\ 8x^2y and -2x^2ydot

Divide : 12x^(2) + 7xy - 12y^(2) by 3x + 4y

Factorise: 4(2x-3y)^(2) - 8x + 12y -3

Solve the following equations for (x - 3)^(2) and (y + 2)^(2) : 2x^(2) + y^(2) - 12x + 4y + 16 = 0 and 3x^(2) - 2y^(2) - 18x - 8y + 3 = 0 .

Find the centre, the lengths of the axes, eccentricity, foci of the following ellipse: (3x^2 + 4y^2 - 12x - 8y + 4) =0

Factorize: x^3+8y^3+6 x^2y+12x y^2

Factorize: x^3+8y^3+6x^2y+12 x y^2

The equation of the circle passing through the point of intersection of the circles x^2+y^2-4x-2y=8 and x^2+y^2-2x-4y=8 and the point (-1,4) is (a) x^2+y^2+4x+4y-8=0 (b) x^2+y^2-3x+4y+8=0 (c) x^2+y^2+x+y=0 (d) x^2+y^2-3x-3y-8=0
