    Step-by-step explanation:

    According to the equation, we have to solve for x:

    x² - 10x + 25 = 35

    x² - 10x + 25 - 35 = 0

    x² - 10x - 10 = 0

    Using Quadric Formula,

    x = - b ±√b²-4ac / 2a

    x = - (-10) ±√ (-10) ² - 4 (1) (-10) / 2 (1)

    x = 10 ±√ 100 + 40 / 2

    x = 10 ±√ 140 / 2

    Taking common "2"

    x = 2 (5±√70) / 2

    Both "2" will cut with each other

    So,

    Now we have

    x = 5 ± √70

    This is the required "X" In the equation
