No. A polynomial equation in one variablel ooks like P(x) = Q(x), where P and Q are polynomials.
Consider polynomial equations x^2 = 3 and x^2 = 1.
Obviously they have real solutions.
Subtract the two polynomial equations:
(x^2 - x^2) = (3 - 1)
0 = 2...
We get the polynomial equation 0 = 2. We call this a polynomial equation because single constants are also by definition polynomials.
Obviously 0 = 2 has no real solution.

Kimberly
Step-by-step explanation:
My mother gave me the name
I think that the answer is 226.194 inches
If the half-life is t, then every t days, the amount of the radioactive isotope will be cut in half.
(1/2)^(number of half-lives) = 3%
number of half-lives = ln(0.03) / ln(0.5)
This gives the number of half-lives as 5.06.
Then 300 days = (5.06)(length of 1 half-life)
length of 1 half-life = 300 / 5.06 = 59.29 days
Answer:
Option (1)
Step-by-step explanation:
Given equation is,
![2^x=1-3^x](https://tex.z-dn.net/?f=2%5Ex%3D1-3%5Ex)
To determine the solution of the equation we will substitute the values of 'x' given in the options,
Option (1)
For x = -0.75
![2^{-0.75}=1-3^{-0.75}](https://tex.z-dn.net/?f=2%5E%7B-0.75%7D%3D1-3%5E%7B-0.75%7D)
0.59 = 1 - 0.44
0.59 = 0.56
Since, values on both the sides are approximately same.
Therefore, x = -0.75 will be the answer.
Option (2)
For x = -1.25
![2^{-1.25}=1-3^{-1.25}](https://tex.z-dn.net/?f=2%5E%7B-1.25%7D%3D1-3%5E%7B-1.25%7D)
0.42 = 1 - 0.25
0.42 = 0.75
Which is not true.
Therefore, x = -1.25 is not the answer.
Option (3)
For x = 0.75
![2^{0.75}=1-3^{0.75}](https://tex.z-dn.net/?f=2%5E%7B0.75%7D%3D1-3%5E%7B0.75%7D)
1.68 = 1 - 2.28
1.68 = -1.28
Which is not true.
Therefore, x = 0.75 is not the answer.
Option (4)
For x = 1.25
![2^{1.25}=1-3^{1.25}](https://tex.z-dn.net/?f=2%5E%7B1.25%7D%3D1-3%5E%7B1.25%7D)
2.38 = 1 - 3.95
2.38 = -2.95
It's not true.
Therefore, x = 1.25 is not the answer.
