Answer:
Step-by-step explanation:
Given equation to us is ,
So , a equation is said to be a quadratic equation if the highest degree of the variable is 2 . On simplifying the Equation ,
![\implies x^2 +\dfrac{1}{x}=4](https://tex.z-dn.net/?f=%5Cimplies%20x%5E2%20%2B%5Cdfrac%7B1%7D%7Bx%7D%3D4%20)
Taking x as LCM ,
![\implies \dfrac{x^2.x + 1 }{x}= 4](https://tex.z-dn.net/?f=%5Cimplies%20%5Cdfrac%7Bx%5E2.x%20%2B%201%20%7D%7Bx%7D%3D%204%20)
Transposing x to RHS .
![\implies x^3 + 1 = 4x](https://tex.z-dn.net/?f=%5Cimplies%20x%5E3%20%2B%201%20%3D%204x%20)
Putting all terms in LHS
![\boxed{\bf \implies x^3 - 4x - 1 = 0 }](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cbf%20%5Cimplies%20x%5E3%20-%204x%20-%201%20%3D%200%20%7D)
Since here the highest degree of the variable is 3 not 2 . So its a cubic equation and not a quadratic equation .

Answer:
(x + 1)(x + 2)
Step-by-step explanation:
Factorise the denominator of the first fraction
x² + 3x + 2 = (x + 1)(x + 2) ← in factored form
The denominator of each fraction must be able to divide into the lcd
Hence lcd is (x + 1)(x + 2)
In order to get the answer for this question you need to times 2 by 10, which equals 20 since it's $2 for each guest. That now leaves her with $20. $26+$20 <u>equals </u><u>$46</u> for the total cost of the retirement party.
