HELP PLEASE!! x3-3x2-10x+24 by x-2. fill into other equation
dalvyx [7]

The solution to the division of the given polynomial expression is:

k = (x+3)(x-4)

<h3>Division of polynomials</h3>

The division of the given polynomial can be determined by using the rational root theorem which is a method that is popularly used in determining the solutions to a polynomial equation.

From the information given:

\mathbf{\dfrac{x^3 -3x^2 - 10x +24}{x-2}}

Using the rational root theorem;

\mathbf{\dfrac{(x-2) \dfrac{x^3 -3x^2 - 10x +24}{x-2} }{x-2}}

\mathbf{\dfrac{(x-2)(x^2 -x-12)}{x-2} }}

Factor: x² - x - 12

\mathbf{\dfrac{(x-2)(x+3)(x-4)}{x-2} }}

Cancel out the common factor (x-2)

\mathbf{=(x+3)(x-4) }}

Let the total number of teachers be x

Given:

The ratio of the number between male and female teachers is 5:9

Then the number of female teachers is 81

So 9/14*x=81

or, x=81/9*14

or, x=9*14

Therefore x=126

So the total number of teachers is 126.

Hence the number of male teachers =

5/14*126

=5*9

=45

Hence, the number of male teachers is 45.
