Answer:
3√2 and -3√2
Step-by-step explanation:
2x^2-36
2(x^2-36)
2(x+3√2)(x-3√2)

First, Use the slope equation to find the slope of the line passing thru these two points:
m=rise/run
Here, the rise is 13-3, or 10, and the run is 7-2, or 5.  Thus, the slope, m, is 10/5, or 2:  m=2.
We want the slope-intercept form, so let's begin with its general form:
y=mx+b.  Substitute the slope 2 for m:  y=2x+b.  Now choose either of the given points.  Arbitrarily I am choosing (2,3).  Then x=2 and y=3.
Substituting these values into y=2x+b:    3 = 2(2) + b, or b= 3 -4, or b = -1.
Then the equation of this line, in slope-intercept form, is y = 2x - 1.
        
             
        
        
        
Given:
The scale of a map is  .
.
The distance between two buildings is 60 miles.
To find:
The distance between the given building on the map.
Solution:
We have,

It means, 80 miles in real life =  on the map.
 on the map.
1 mile in real life =  on the map.
 on the map.
60 mile in real life =  on the map.
 on the map.
                               =  on the map.
 on the map.
                               =  on the map.
 on the map.
Therefore, the buildings are  apart on the map.
 apart on the map.
