Distributive Property is when you have an equation similar to this: 7(9+6c). And expanded form for 475 is 400+70+5, so the answer would be 9(400+70+5), because it has both expanded form and distributive, and it's also how you'd solve regardlessly.

Answer:
x = 2 ±
Step-by-step explanation:
Given
y = x² - 4x - 9
To find the zeros, set y = 0, that is
x² - 4x - 9 = 0 ( add 9 to both sides )
x² - 4x = 9
To complete the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(- 2)x + 4 = 9 + 4, that is
(x - 2)² = 13 ( take the square root of both sides )
x - 2 = ± ( add 2 to both sides )
x = 2 ± ← exact solutions
