  • [tex]2a + b \\ = 2(2xy - 3 {x}^{2} {y}^{2} ) + ( {x}^{2} {y}^{2} - 2xy) \\ = 4xy - 6 {x}^{2} {y}^{2} + {x}^{2} {y}^{2} - 2xy \\ = 2xy - 5 {x}^{2} {y}^{2} [/tex]

    ————————————————————
    A = 2xy - 3x²y²
    2A = 4xy - 6x²y²
    B = x²y² - 2xy
    2A + B
    = 2 ( 2xy - 3x²y² ) + ( x²y² - 2xy )
    = 4xy - 6x²y² + x²y² - 2xy
    = - 5x²y² + 2xy ✔️
