Step-by-step explanation:
Given
x² - 9x + 4 = 0 ( subtract 4 from both sides )
x² - 9x = - 4
Using the method of completing the square
Add ( half the coefficient of the x- term )² to both sides
x² +2 (- )x +
= - 4 +
(x - )² =
Take the square root of both sides
x - = ±
= ±
Add to both sides
x = ±
← exact solutions
To solve this problem, you simply need to divide 90 by 18, to find the number of paid months, then add the two free months.
So:
= 5 paid months
5 paid months + 2 free months = 7 months that you will be able to play
