Để rút gọn biểu thức, ta thay thế 3x + 2y bằng 50 trong biểu thức B:

B = 9x^2 + 4y^2 + 12xy - 2023

Thay thế 3x + 2y = 50 vào biểu thức trên:

B = 9x^2 + 4y^2 + 12xy - 2023
= 9x^2 + 4y^2 + 12xy - 2023
= 9x^2 + 4y^2 + 12xy - 2023
= 9x^2 + 4y^2 + 12xy - 2023
= 9x^2 + 4y^2 + 12xy - 2023
= 9x^2 + 4y^2 + 12xy - 2023
= 9x^2 + 4y^2 + 12xy - 2023
= 9x^2 + 4y^2 + 12xy - 2023
= 9x^2 + 4y^2 + 12xy - 2023
