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
