Answer:
x ≈ 1.32, x ≈ - 5.32
Step-by-step explanation:
Given
x² + 4x - 7 = 0 ( add 7 to both sides )
x² + 4x = 7
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(2)x + 4 = 7 + 4
(x + 2)² = 11 ( take the square root of both sides )
x + 2 = ± 
( subtract 2 from both sides )
x = - 2 ± 
Thus
x = - 2 - ≈ - 5.32 ( to 2 dec. places )
x = - 2 + ≈ 1.32 ( to 2 dec. places )

Answer:
Hi there!
Your answer is;
17/6 <em><u>OR</u></em> 2 & 5/6
Step-by-step explanation:
(-5+1)/6 - (-8+1)/2
First, simplify in parentheses!
-4/6 - -7/2
Next, change the symbol of 7/2 because two negatives make a positive!
-4/6 +7/2
Next, change the denominators so they both have the same
-4/6 + 7/2
× 3/3
-4/6 + 21/6
Simplify!
17/6
<u>OR</u>
2 & 5/6
Hope this helps
