(- 4x-3y Square) (3Y square-4x)

(- 4x-3y Square) (3Y square-4x)

(- 4x-3y Square) (3Y square-4x)
=-(4x + 3Y Square) (3Y square - 4x)
=-(9y quartic-16x Square)
=16x squared-9y quartic

Square of (x + 3Y) - square of 2 (x + 3Y) (4x-3y) + (4x-3y)

The original formula = [(x + 3Y) - (4x-3y)] ²
=(-3x+6y)²
=9(x-2y)²

(4x-3y) & # 178; perfect square
Is it equal to 16x & # 178; - 24xy-9y & # 178; or 16x & # 178; - 24xy + 9y & # 178;? Write down the step-by-step problem-solving process

(4x-3y)²
=(4x-3y)(4x-3y)
=(4x)²-2×3y×4x+(3y)²
=16x²-24xy+9y²
