Answer: x² - 2x - 3
Explanation:
What is FOIL? The FOIL method is used to multiply two binomials.
F ➜ First
O ➜ Outer
I ➜ Inner
L ➜ Last
Let us break it down into each piece by multiplying, following the pattern.
F ➜ x * x ➜ x²
O ➜ x * 1 ➜ x
I ➜ x * -3 ➜ -3x
L ➜ -3 * 1 ➜ -3
Lastly, we add these pieces together.
x² + x - 3x - 3 = x² - 2x - 3
