    4 (5x² - 9x + 7) + 2 (-10² + 18x - 13)

    Distribute 4 inside the parentheses.

    20x² - 36x + 28 + 2 (-10² + 18x - 13)

    Find 10 to the power of two.

    20x² - 3y6x + 28 + 2 (-100 + 18x - 13)

    Combine like terms inside the parentheses (-100 - 13).

    20x² - 36x + 28 + 2 (-113 + 18x)

    Distribute 2 inside the parentheses.

    20x² - 36x + 28 + (-226 + 36x)

    Rewrite as - 226 and + 36x; remove the parentheses.

    20x² - 36x + 28 - 226 + 36x

    Combine like terms. The - 36x and 36x cancel each other out.

    20x² - 198

    is your answer.
