Answer: p(x) = a (x-b)(x-c)(x-d)

Step-by-step explanation:

The first step is to determine the degree of the polynomial.

It shall depend totally on the linear factors given for the polynomial.

If there is one, it is a linear polynomial.

If there are 2, then it is a quadratic polynomial.

If there are three then it shall be a cubic polynomial.

Now let us assume that there are three linear factors.

We multiply those factors and write the polynomial.

If x-b, x-c & x-d are the factors we write

p(x) = (x-b)(x-c)(x-d)

But as we may have a leading coefficient so we write the polynomial as

Then we go on to expand this to get the polynomial in the standard form.

Answer with Step-by-step explanation:

First we find the degree of polynomial.

Consider two linear factors

(x-a) and (x-b)

Multiplying these two factors to get the polynomial.

p(x)=(x-a)(x-b)=x^2-(a+b)x+ab

There are two linear factors .

Therefore, the degree of polynomial is 2 and the polynomial is quadratic.

Degree of polynomial=Number of linear factors

If the linear factors are three then the polynomial formed by multiplying theses factors .

Then, we get the polynomial of degree 3 and the polynomial is cubic polynomial.

It we have four linear factors.

After multiplying these four factors, we get a polynomial of degree 4.

The polynomial is bi quadratic.

Yakvenalex [24]

Answer:

6

Step-by-step explanation:

Speed = Distance/time

Therefore time must = distance/speed

Since the two students are running apart from eachother, we can add their speeds together.

Also we can subtract 10 feet from our goal of 1870 since they're already 10 feet apart.

1860 feet/(150+1650) feet per minute

We can cancel out the feet since it's a common term.

And we're left with 6 minutes.
