Use completing the square to solve (x – 12)(x + 4) = 9 for x. x = –1 or 15 x = 1 or 7
Answers
(x - 12)(x + 4) = 9 x² + 4x - 12x - 48 = 9 x² - 8x - 48 = 9 |add 48 to both sides x² - 8x = 57 x² - 2x · 4 = 57 |add 4² to both sides x² - 2x · 4 + 4² = 57 + 4² |use (a - b)² = a² - 2ab + b² (x - 4)² = 57 + 16 (x - 4)² = 73 ⇔ x - 4 = √73 or x - 4 = -√73 |add 4 to both sides
x = 4 + √73 or x = 4 - √73
You can model the population of a certain city between the years 1965 and 1995 by the radical function P(x)= 75,000 cubed root of (x-1940) . Using this model, in what year was the population of that city 245,000?
Answers
P(x)= 75,000*(x-1940)^(1/3) then the P = 245000 means
245000 = 75,000*(x-1940)^(1/3) (245000/75000)^3 + 1940 = X X ≈ 1974
