Answer:
x² - 2x + 1
Step-by-step explanation:
We want to express (x - 1)² as a trinomial. In other words, we want to expand this out.
(x - 1)² = (x - 1)(x - 1)
We use FOIL (First, Outer, Inner, Last). The First terms are x and x. Multiply:
x * x = x²
The outer terms are x and -1. Multiply:
x * (-1) = -x
The inner terms are -1 and x; multiply:
(-1) * x = -x
The last terms are -1 and -1; multiply:
(-1) * (-1) = 1
Add all these together:
x² + (-x) + (-x) + 1 = x² - 2x + 1

Answer:
1/12
Step-by-step explanation:
Given that :
Spinner has four colors (purple, green, blue, or yellow)
Dice has six faces (1, 2, 3, 4, 5, 6)
Probability = required outcome / Total possible outcomes
Probability of green, p(green) = 1/ 4
P(rolling 5 or 6) = p(5) + p(6) = 1/6 + 1/6 = 2/6 = 1/3
P(green) and then rolling a 5 or 6
P(green) * p(rolling 5 or 6)
(1/4) * (1/3) = 1/12
