Answer:
The rational roots of the equation are:
x= -1.10355
x= 0.148953
x= 0.706883
x= -1
Step-by-step explanation:
We have to find the rational solutions of the algebraic equation:
This equation could also be written as:
for finding the roots of the equation we have to find the possible values of x.
Clearly the equation has 8 roots as the degree of the equation is 8.
from the graph of the following function we could see that the rational roots of the function are:
x= -1.10355
x= 0.148953
x= 0.706883
x= -1
The rest 4 roots of the equation are the complex roots.
The equation of a line in a point-slope form is
where m is a slope of the line and
is the point that line is passing through.
If slope m=3, then the equation will be
The line is passing through the point (1,4), then the equation of the line is:
