A) <span>5x^2-13x-6

 1. First, you must find the roots of the quadratic equation, by applying the quadratic formula, which is:

 x=-b</span>√(b²-4ac)/2a
<span>
 2. The roots are:

 x1=3
 x2=-2/5

 3. Then, you have:

 5(x-3)(x+2/5)

 4. When you simplify, you obtain:

 (x-3)(5x+2)

 B) </span>4x^4-28x^3+48x^2<span> 

 1. First, you must factor the common term, which is 4x</span>^2. Then:
<span>
 4x</span>^2(x^2-7x+12)
<span>
 2. Now, you must apply the quadratic formula to obtain the roots of the quadratic equation: </span>x^2-7x+12. Then, you have:

 x1=4
 x2=3

 3. Finally, you obtain:

 4x^2(x-4)(x-3)

Answer:

<em>C. Omitted variable bias </em>

Step-by-step explanation:

In mathematics and statistics, omitted-variable bias (OVB) happens if one or more important variables is left out by a statistical model.

The bias results in the equation being related to the expected effects of the included variables by the influence of the excluded variables.

Find the distance between the two points in simplest radical form. (4,4) and (8,-3)
Juliette [100K]

Answer:

2/5

Step-by-step explanation:

If you have two point of the form(x_1,y_1) and (x_2,y_2) then the distance between these points is d=√(x_1-x_2)^2+(y_1-y_2)^2

In this case:

d=/(-8-(-6))^2+(-2-2)^2

d=/(-8+6)^2+(-4)^2

d=/(-2)^2+16

d=/4+16

d=/20

d=2/5
