Answer:
The polynomial equation that cannot be solved using the quadratic formula: Option2: ![x^2-2x^3-5=0](https://tex.z-dn.net/?f=x%5E2-2x%5E3-5%3D0)
Step-by-step explanation:
First of all we have to learn what a quadratic polynomial is.
A polynomial or equation of degree 2 is called a quadratic equation. Quadratic formula is used to solve quadratic equations.
The quadratic equation is of the form:
![ax^2+bx+c = 0](https://tex.z-dn.net/?f=ax%5E2%2Bbx%2Bc%20%3D%200)
From the given options, only option 2 doesn't have degree 2 so it is not a quadratic polynomial.
Hence,
The polynomial equation that cannot be solved using the quadratic formula: Option2: ![x^2-2x^3-5=0](https://tex.z-dn.net/?f=x%5E2-2x%5E3-5%3D0)
Answer:
27 years old
Step-by-step explanation:
let Sydney's age be x, then
Devaughn's age is 3x ( three times Sydney's )
The sum of their ages is 108, thus
x + 3x = 108
4x = 108 ( divide both sides by 4 )
x = 27
Sydney is 27 years old
