1.

The value of (x-2y)(y-3x)+(x+y)(x-3y)-(y-3x)(4x-5y)

Answer»

Hey here is your answer...☺️

(x - 2y)(y - 3X) + (x + y)(x - 3y) - (y - 3x)(4x - 5Y)

(-3x^2 + XY - 2y^2 + 6xy) + (x^2 - 3xy +xy - 3y^2) - (4xy - 5y^2 - 12x^2 + 15xy..

- 3x^2 + 7xy - 2y^2 + x^2 - 2xy - 3y^2 - 4xy + 5y^2 + 12x^2 - 15xy

(- 3x^2+12x^2 +x^2) - (2y^2 - 3y^2 + 12 y^2 )+(7xy - 2xy - 4xy - 15xy)

10x^2 +7y^2 - 14XY...Ans

I HOPE IT WILL HELP YOU ☺️

thnx for asking ur QUESTION ✌️✌️
