Find all the zeros of the polynomial function. x^3 + 2x^2 -5x-6 f(x) a) (-3) b) (-2, 1, 3 c) (-3, -1, 2) d) -1) e) none

Flauer [41]

Answer:1,2,3

Step-by-step explanation:

F(x)= $x^{3}$ +2 $x^2$ - $5x$ - $6$ =0

disintegrating 2 $x^2$ to $x^2$ + $x^2$

$x^{3}$ + $x^2$ + $x^2$ - $5x-6$ =0

$x^2$ $\left ( x+1\right )$ + $x^2$ -5x-6=0

$x^2$ $\left ( x+1\right )$ + $x^2$ -6x+x-6=0

$x^2$ $\left ( x+1\right )$ + $\left (x-6 \right )$ $\left ( x+1\right )$ =0

$\left ( x+1\right )$ $\left ( x^2+x-6\right )$ =0

$\left ( x+1\right )$ $\left ( x^2+3x-2x-6\right )$ =0

$\left ( x+1\right )$ $\left ( x+3\right )$ $\left ( x-2\right )$ =0

A 10

Deffense [45]

Answer:

The equation representing Number of miles in each section is $\frac{10}{4}$

Total Number of miles in each section is 2.5 miles.

Step-by-step explanation:

Given:

Total Miles bike race = 10 Miles

Number of sections = 4

Now we know that sections are divided in equal parts;

So Number of miles in each section can be calculated by dividing total miles of bike race with Number of section race.

The Number of miles in each section = $\frac{\textrm{Total distance in miles}}{\textrm{Number of sections}}$

Number of miles in each section = $\frac{10}{4}$

The equation representing Number of miles in each section is $\frac{10}{4}$

Solving the above equation we get;

Number of miles in each section = $\frac{10}{4}= 2.5 \ miles$

Hence Total Number of miles in each section is 2.5 miles.
