Answer:
x^2+5x-6
a = 1  b = 5 and c = -6
Using the quadratic formula:
x = [-5 +- sq root (25 -4 * 1 *-6) ] / 2 * 1
x = [-5 +- sq root (49)] / 2
x = [-5 +- 7] / 2
x1 = 1
x2 = -6
 
Step-by-step explanation:
 
        
             
        
        
        
The standard form of this equation is 

The slope of two parallel lines i the same, so the slope of the line we're looking for is also 

Since the line passes through 

, the equation is:
