Evaluate : (2x-y+3z)(4x^(2)+y^(2)+9z^(2)+2xy+3yz-6xz)

Evaluate: (2x+3y)^(2)( ii) (2x-3y)^(2)(2x+3y)2x-3y)

Evaluate: 3x + 23x^2 + 6y^2 + 2x + y^2 + " ______ " = 5x + 7y^2 .

If ((2x-y)/(x+2y))=(1)/(2), then find the value of ((3x-y)/(3x+y))

Find the continued product: (2x+3y)(2x-3y)(4x^(2)+9y^(2))

Find the eccentricity of the conic 4(2y-x-3)^(2)-9(2x+y-1)^(2)=80

If x=4 and y=1, find the value of ((x)/(2)-(y)/(3))((x^(2))/(4)+(xy)/(6)+(y^(2))/(9)) .

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) =?

Find the products: (x+3y)(x^(2)-3xy+9y^(2))

Simplify: [5-3x+2y-(2x-y)]-(3x-7y+9)
