    x²+5x-10=0

    x² + (2-7) x-10=0

    x²+2x-7x-10=0

    x (x+2) - 7 (x+2) = 0

    =x+2=0

    =x=-2

    =x-7=0

    =x=7

    x = - 2 or 7

    Step-by-step explanation:

    x² - 5x - 14 = 0

    x² - 7x + 2x - 14 = 0

    x (x - 7) + 2 (x - 7) = 0

    (x + 2) (x - 7) = 0

    x = - 2 or 7
