(3) 2 square of. 4x - 3xy = 2 square of 2Y - 2 (2 square of 2x - 5xy + 2 square of Y) (where x = 2, y = 3)

(3) 2 square of. 4x - 3xy = 2 square of 2Y - 2 (2 square of 2x - 5xy + 2 square of Y) (where x = 2, y = 3)

4x^2-3xy=2y^2-2(2x^2-5xy+y^2)
4x^2-3xy=2y^2-4x^2+10xy-2y^2
8x^2-13xy=0
When x = 2.y = 3
Original formula = 32-13 * 2 * 3 = - 46
Note: 4x ^ 2 is the square of 4x
I hope my answer is useful to you. Have a good time
