Solve each quadratic equation by factoring and using the zero product property. x^2 + 18x = 9x

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number?

According to a study conducted in 2015, 18% of shoppers said that they prefer to buy generic instead of name-brand products. suppose that in a recent sample of 1500 shoppers, 315 stated that they prefer to buy generic instead of name-brand products. at a 5% significance level, can you conclude that the proportion of all shoppers who currently prefer to buy generic instead of name-brand products is higher than .18? use both the p-value and the critical-value approaches.
