Answer:
Step-by-step explanation:
Given is a differential equation of III order,
The characteristic equation would be cubic as
By trial and error, we find that
Thus m=2 is one solution
Since given that 
is one solution we get
m = -4+i and hence other root is conjugate 
Hence general solution would be
Answer:
- Identify the variable term on one side and subtract it from both sides.
Step-by-step explanation:
We assume the question relates to terms containing the variable you want to solve for.
In general, you want to rearrange the equation so there is only one term containing the variable of interest. This can be accomplished by identifying the variable term(s) on one side of the equation and subtracting that from both sides of the equation.
For <u>example</u>, consider ...
ax + b = cx + d
<u><em>First step</em></u>
Terms ax and cx are on opposite sides of the equal sign. If we're solving for x, we need to remove one of those terms. We can do that by subtracting cx from both sides of the equation:
ax -cx +b = cx -cx +d . . . . . showing the subtraction
x(a -c) +b = d . . . . . . . . . . . . .the simplified result of the subtraction
_____
<em>Additional comment</em>
Please note that the coefficient of the variable is now (a-c). This will be <em>positive</em> if the term we subtracted (cx) had the smaller of the two coefficients (c < a). While not essential, this is a convenient choice to make when choosing which term to subtract.
The answer is 20-3x=-7 explanation
A number line is used in the mathematical positioning of real numbers that include the numbers from positive infinity to negative infinity. This includes rational, irrational, fractions, and whole numbers. In this case, we are given with an expression that we have to reduce to lowest terms: negative seven and one over two and +1. The first one is equal to -7.5 while the other one is equal to +1. Positive numbers lie on the right side of zero (center of the line) while negative numbers lie on the left on the other hand. -7.5 lies between -8 and -7 while +1 lies exactly between 0 and 2. Both of which are positive numbers.
