1Write all of the following statement(s) that apply to the following polynomial: -8x + 2x2 – 3 It is a binomial. It can be evaluated at x = -1/3 It has a coefficient of 8. It is quadratic.

OpenStudy (anonymous):

How many terms are there 1 or 2 or 3 tell me first??

OpenStudy (anonymous):

3

OpenStudy (anonymous):

So apply this one: Binomial means having two terms.. Since it has 3 so first option gets cancel...

OpenStudy (anonymous):

What is here the highest power??

OpenStudy (anonymous):

2

OpenStudy (anonymous):

Yes.. Polynomial having degree 2 is called Quadratic.. So last one is right..

OpenStudy (anonymous):

And here is x coefficient is -8 and not 8 also the coefficient of \(x^2\) is 2.. So third option also gets cancel..

OpenStudy (anonymous):

so can it be evaluated at x= -1/3 ?

OpenStudy (anonymous):

Don't go this way..

OpenStudy (anonymous):

Evaluated means can we find the values by plugging -1/3 in the expression yes we can evaluate this..

OpenStudy (anonymous):

I got 0

OpenStudy (anonymous):

How???

OpenStudy (anonymous):

Show me your work..

OpenStudy (anonymous):

even if you solved for the value of x, you will not get -1/3

OpenStudy (anonymous):

We have to evaluate this and not solve @panlac01

OpenStudy (anonymous):

Simply put x = -1/3 in the expression: What do you get tell me??
