    Answer:

    First:  x^2

    Outer:  -5x

    Inner:  -7x

    Last:  35

    Final Result:  x^2 – 12x + 35

    Step-by-step explanation:

    Step 1:  Foil the expression

    (x – 7)(x – 5)

    To foil, you multiply the first my the first, the first by the second, the second by the first, and the second by the second.

    (x – 7)(x – 5)

    (x * x) + (x * -5) + (-7 * x) + (-7 * -5)

    1 by 1     1 by 2     2 by 1     2 by 2

    x^2  –  5x   –   7x  +   35

    first   outer   inner   last

    x^2 – 12x + 35

    Answer:  x^2 – 12x + 35
