Solve the polynomial equation. in order to obtain the first root, use synthetic division to test the possible rational roots. x3+2x2-5x-6= 0 o1) (-1) 2) {-3, -1, 2} 3) (-3) 4) [-2, 1,3)

The possible solution of the polynomial equation are the following values (-1,2,-3)

Step-by-step explanation:

We use synthetic division to find the roots which satisfy the equation mentioned before:

1. First we compile the list of all possible rational roots using the Rational Zero'  Theorem

The factors of the constant term 6 are: ±1, ±2, ±3, ±6

The factors of the leading coefficient 1 are ±1

So now we divide all the factors of 6 by all factors of 1 to get the following list {±1, ±2, ±3, ±6)

2. Now we start testing values until we find the roots, the complete solution is attached in pdf format:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
