Answer:

(x + \frac{7}{2} )² - \frac{1}{4} = 0

Step-by-step explanation:

Given

x² + 7x + 12 = 0

To complete the square

add/subtract ( half the coefficient of the x- term)² to x² + 7x

x² + 2(\frac{7}{2} )x + \frac{49}{4} - \frac{49}{4} + 12 = 0

(x + \frac{7}{2} )² - \frac{49}{4} + \frac{48}{4} = 0 , that is

(x + \frac{7}{2} )² - \frac{1}{4} = 0

So -1/4 would be the slope
m= -1/4
