Answer:

2(3x² - 4x - 5)

Step-by-step explanation:

f(x)= 3x^{2} + 2x

∴ 2f(x-1) = 2 * { 3 *(x-1)^{2} + 2 * (x - 1)} = 2 * {3 * (x² - 2x - 1²) + 2x -2}

                                                            = 2 * {3x² - 6x - 3 + 2x - 2}

                                                           = 2 * (3x² - 4x - 5)

                                            => 2f(x-1) = 2(3x² - 4x - 5)
