What are the roots of the polynomial equation x3 - 6x= 3x2 - 8? Use a graphing calculator and a system of equations
1 answer:
Answer:
Hence, the roots of the polynomial equation are:
-2, 1, 4
Step-by-step explanation:
We are asked to find the roots of the polynomial equation:
We can also equate this equation to y to obtain a system of equation as:
and
Hence, the roots of the polynomial; equation are the x-values of the point of intersections of the graph of the system of equations.
Hence, the point of intersection of the two graphs are:
(-2,4), (1,-5) and (4,40)
Hence, the roots of the polynomial equation are:
-2, 1, 4

Answer:
Asanji drove for hours before Huong caught up
Step-by-step explanation:
Let the time for which Asanji drove alone is "X" hours
Asanji and Huong met after three hours of driving of Huong.
Total time for which Asanji drove hours
Thus, distance travelled by Asanji in hours is equal to distance travelled by Huong in
hours
On solving the above equation, we get -
Asanji drove for hours before Huong caught up
