    So the factors of the given are:

    (x-4) and (x-9).

    The factored form of the given expression is (x-4) (x-9).

    Step-by-step explanation:

    To factore the given quadratic with leading coefficient one, you must find two numbers that add to be and multiply to be c.

    a=1

    b=-13

    c=36

    So we need two numbers that multiply to be 36 and add to be - 13.

    These numbers are - 4 and - 9 since

    (-4) (-9) = 36 and - 4+-9=-13.

    So the factors of the given are:

    (x-4) and (x-9).

    The factored form of the given expression is (x-4) (x-9).
