The quadratic formula solves for X so u can plot it on a graph. it solves for X by subtracting and another way by Adding so you get 2 x's

Starcraft
a) Probability of losing at most 2 games = 33%
b) Probability of winning at least 4 games = 67%
Step-by-step explanation:
a) To lose 2 out of 6 games, the probability is 2/6 x 100 = 33.333%
b) To win at least 4 games out of 6, the probability is 4/6 x 100 = 66.667%
c) Since Serral is playing 6 games, for her to lose at most 2 of the games is described as a probability in this form 2/6 x 100. This shows the chance that 2 of the games out of 6 could be lost by Serral. On the other hand, the probability of Serral winning at least 4 of the 6 games is given as 4/6 x 100. It implies that there is a chance, 4 out of 6, that Serral would win the game.
X^5 = 1024 = 4^5
Therefore, x = 4.
Given, (-1/7)^-x = -1/343
(1/7)^-x = 1/343
(1/7)^-x = (1/7)^3
-x = 3
x = -3
