Answer:
1. x² + 10x + 9
2. x² - 4x - 5
Step-by-step explanation:
(x + 1)(x + 9)
F: (x)(x) = x²
O: (x)(9) = 9x
I: (1)(x) = x
L: (1)(9) = 9
x² + 9x + x + 9
x² + 10x + 9
(x + 1)(x - 5)
F: (x)(x) = x²
O: (x)(-5) = -5x
I: (1)(x) = x
L: (1)(-5) = -5
x² + (-5x) + x + (-5)
x² - 5x + x - 5
x² - 4x -5
I hope this helps.
