The equation can be rewritten as: Log(x*(x+5))=Log=(6x+12)
so x(x+5)=6x+12
x^2+5x=6x+12
x^2-x-12=0
(x+3)(x-4)=0
x=-3 or x=4
x cannot be negative here, so x=4 is the only solution
Answer:
The solution to the equation are x = 5.089 and x = -0.589
Step-by-step explanation:
Given:
x(at the power of 2) = 6 + 9x
To Find:
The solution of the equation = ?
Solution:
The given equation can be written as
=>
=>
=>
Using the quadratic formula,
where
a= 2
b = -9
c = -6
Substituting these values,
![x = \frac{-(-9)\pm \sqrt{(81) -4(-12)}}{2(2)}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B-%28-9%29%5Cpm%20%5Csqrt%7B%2881%29%20-4%28-12%29%7D%7D%7B2%282%29%7D)
![x = \frac{-(-9)\pm \sqrt{81+48}}{4}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B-%28-9%29%5Cpm%20%5Csqrt%7B81%2B48%7D%7D%7B4%7D)
![x = \frac{-(-9)\pm \sqrt{129}}{4}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B-%28-9%29%5Cpm%20%5Csqrt%7B129%7D%7D%7B4%7D)
![x = \frac{-(-9)\pm 11.357}{4}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B-%28-9%29%5Cpm%2011.357%7D%7B4%7D)
![x = \frac{9 \pm 11.357}{4}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B9%20%5Cpm%2011.357%7D%7B4%7D)
![x = \frac{9 - 11.357}{4}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B9%20-%2011.357%7D%7B4%7D)
x =5.089 x = -0.589
C.
If you properly distribute C it will give you the above equation.
1/4 * -x = -1/4x
AND
1/4 * 2 = 1/2
