Roots: - √5 , √5, and - 3
=> these are factors of the polynomial: (x + √5), (x - √5), and (x + 3).
Multiply those three factors:
(x + √5) (x - √5) ( x + 3) = [x^2 - 5] ( x + 3 ) = x^2 + 3x^2 - 5x - 15
Therefore the polynomial x^2 + 3x^2 - 5x - 15 is a polynomial with the given roots.
Answer: option B. x^3 + 3x^2 - 5x - 15

Answer: 5.5 quarts = 22 cups
Step-by-step explanation:
1 cup = 4 cups
to convert cups to quart, just multiply by 4
5.5 x 4 = 22
Answer:
Area = 5/6 of a foot^2
Step-by-step explanation:
Formula
Area of a trapezoid (formula) = 1/2 (b1 + b2)*h/2
Givens
- b1 = 2 feet
- b2 = 3 feet
- h = 1/3 foot
Solution
Area = 1/2(2 + 3)*1/3
Area = 1/2(5)* 1/3
Area = (1/2 * 1/3) * 5
Area = (1/6) * 5
Area = 5/6
