Answer:
x = - 3 ± 
Step-by-step explanation:
x² + 6x + 7 = 0 ( subtract 7 from both sides )
x² + 6x = - 7
using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(3)x + 9 = - 7 + 9
(x + 3)² = 2 ( take square root of both sides )
x + 3 = ±
( subtract 3 from both sides )
x = - 3 ± 
350/100 = 350%
350% is the percentage of 50 over 100
A Probability near 1 Indicates an Unlikely Event . I'm Guessing
Slope = y2 - y1 / x2 - x1
= 8-4 / 3-2
= 4 / 1
= 4
