    Answer:

    x – 5

    Step-by-step explanation:

    Given the function x² – 25, we are to find the quotient when divided by x + 5

    According to different of two square

    a^2 – b^ 2 = (a+b) (a-b)

    Employing this to the question;

    x² – 25, = (x+5)(x-5)

    From the expansion above, we can see that the other terms is x-5, hence the required quotient is x-5
