Rewrite the polynomial-9x^5+36x^4+189x^3 in factored form, using the factoring method method you prefer.

The polynomial 9x^5+36x^4+189x^3 in factored form is $-9 x \times x \times x \times(x-7) \times(x+3)$

<u>Solution:</u>

Given, polynomial equation is $-9 x^{5}+36 x^{4}+189 x^{3}$

We have to find the factored form of the above given polynomial equation.

Let us solve it by grouping.

Now, take the polynomial ⇒ $-9 x^{5}+36 x^{4}+189 x^{3}$

By taking common term out, we get

$\rightarrow-9 x^{3}\left(x^{2}-4 x-21\right)$

$\rightarrow-9 x^{3}\left(x^{2}-(7-3) x-7 \times 3\right)$

Grouping the terms we get,

$\rightarrow-9 x^{3}\left(\left(x^{2}-7 x\right)+(3 x-7 x^3)\right)$

Taking common terms out from each group,

$\rightarrow-9 x^{3}(x(x-7)+3(x-7))$

$\Rightarrow-9 x^{3}((x-7)(x+3))$

$\rightarrow-9 x \times x \times x \times(x-7) \times(x+3)$

Thus the factored form of polynomial is found out

Miss Ferguson recorded 17 absences the first 30 days of school. During the last 60 days of school, she recorded 42 absences. Are

Sloan [31]

Answer:

No, they are not

Step-by-step explanation:

The rate can be described in terms of absences per day.

Now in the first 30 days, they were 17 absences. The rate would thus be number of absences divided by number of days and that is 17/30

In the second run, there were 42 absences in the recent 60 days, rate here would be 42/60 and that is 21/30

Thus, the rates are not equivalent
