` 4 (x-y) ^(2) -12 (x-y)(x+y)+9 (x+y)^(2)`

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

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

1 + 5x + 3y = 9 2x 3y = 12 X = (x, y) - 4

12xy (9x ^ (2) -16y ^ (2)) -: 4xy (3x + 4y)

12xy(9x^2-16y^2) -: 4xy(3x + 4y) .

If (x+y) = 12 and (x-y) = 4 then (2x - 4y) = ?

Evaluate : (viii) (3x + 4y) (3x -4y) (9x^2 + 16y^2)

Solve : (2x)(3)+(y/4=12 , (4x)/3-(9y)/4=2

(a) Draw the rough sketch and find the area of the region included between the parabolas : (i) y ^(2) = 4x and x ^(2) = 4y (ii) y ^(2) = 9x and x ^(2) - 9y (iii) y ^(2) = 16x and x ^(2) = 16y. (b) Find the ratio in which the area bounded by the curves y ^(2) = 12x and x ^(2) = 12y is divided by the line x =3.
