The number of solutions of a rational equation depends on the power (or degree) of the equation (that is, the highest power to which the variable is raised) and the domain. In the complex domain, each rational equation of power n has n solutions. It is, however, possible that two or more of these solutions are coincident - or "multiple zeros". In the real domain, the number of solutions can fall in pairs. So an equation of power 7 will always have 7 complex solutions but it can have 7, 5, 3 or 1 real solutions. (Real numbers are a subset of complex numbers).
Another way of seeing this is through factorisation:
The equation x3 + x2 - 10x + 8 = 0 can be factorised into (x + 1)*(x - 2)*(x - 4) = 0
Now the product of three numbers is 0 is any one of them is 0.
That is, if x + 1 = 0 or if x - 2 = 0 or if x - 4 = 0
Thus the equation has the solutions: x = - 1, x = 2 or x = 4.
The equation of order n can have at most n real binomial factors. (Any more and the biggest power of x would be bigger than n). And again, in the complex domain, using the binomial equation (and equivalents), it must have n binomial factors.
dont put waste in water
To solve linear equations, you always use the inverse operations
I dont know the answer
Well chemical equations can help us understand how a certain substance is made and what combines with what to make it using symbol and word equations but if you dont know your elements it can be a problem
For the people that are trying to figure out if its irrational or rational, its IRRATIONAL
you dont...
i dont think war is a solution in any case
first ask yourself why? is the reason logical? if it is, tell it to your girlfriend. if she is a rational girl and if your reason is rational, she would probably understand.
You should be super happy but be rational and dont waste your money.
i think she is single and dont have any boyfriend
-52 is a rational number because it can be expressed as a fraction in the form of -52/1
Dont talk ok
