`(5x+3y)(5x-3y)(25 x^2+9y^2)`

(5x + 3y) (5x-3y) (25x ^ (2) + 9y ^ (2))

Factorize :7(2x+5)+3(2x+5)(x+2)y+(x+2)x5a(2x+3y)-2b(2x+3y)8(5x+9y)^(2)+12(5x+9y)

The value of (5x-3y)^(2)-(5x+3y)^(2) when x=-1,y=sqrt(1/(25)) is

If (3x -4y) : (2x -3y) = (5x -6y) : (4x -5y) , find : x : y .

Factorise 25x^(2) - 30xy + 9y^(2) . The following steps are involved in solving the above problem . Arrange them in sequential order . (A) (5x - 3y)^(2) " " [ because a^(2) - 2b + b^(2) = (a-b)^(2)] (B) (5x)^(2) - 30xy + (3y)^(2) = (5x)^(2) - 2(5x)(3y) + (3y)^(2) (C) (5x - 3y) (5x - 3y)

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) =?

Using intergration, find the area of the region: {(x,y) : 25x^2 + 9y^2 le 225, 5x + 3y ge 15}
