Answer:
P(x) =
- 7x² + 12
Step-by-step explanation:
Given zeros x = 2, x = - 2, x =
, x = - 
Then the factors are (x - 2), (x + 2), (x -
), (x +
)
and the polynomial is the product of the factors, that is
P(x) = (x - 2)(x + 2)(x -
)(x +
) ← expand in pairs using FOIL
= (x² - 4)(x² - 3) ← distribute
=
- 3x² - 4x² + 12 ← collect like terms
=
- 7x² + 12
To do this, change into common denominators. The common denominator is 21 so change the problem from 1/3 + 1/7 to 7/21 + 3/21. This gives you 10/21. It is already in simplest form.
The 24 ounce one ig because if you divide 7.50 by 15 you’ll find out that it’s 0.50€ per ounce. You’re saving money and getting more for the 25 pack because it should originally be $12.50 but they are giving you 10 more ounces for just $11.75
