The solution to the quadratic equation by completing the square is x = -1 + √3, x = -1 - √3
<h3>What is a quadratic equation?</h3>
Any equation of the form 
where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
We have a quadratic equation:
x² + 2x - 2 = 0
x² + 2x + 1 - 1 - 2 = 0
(x + 1)² - 3 = 0
(x + 1)² = 3
x + 1 = ± √3
x = -1 ± √3
Thus, the solution to the quadratic equation by completing the square is x = -1 + √3, x = -1 - √3

Answer:
There can be 9 arrays.
Step-by-step explanation:
We are asked that the number of arrays that Courtney can make with 36 photos.
The dimensions of the possible arrays are
Here, the array with 1 row by 36 columns and 36 rows by 1 column are different. (Answer)
divide distance by speed
equation: time = distance / speed
120/8.5 = 14.117 seconds
The question gives you 4 different numbers that could be x, so you have to replace each x in each problem and solve. If the two answers are equivalent, that is your answer. For the first one, 6 times 2 is 12, minus 2 is 10. 5 times 2 is 10, plus 3 is 13. 10 is not equal to 13, so that is not the answer. For 5, 6 times 5 is 30, minus 2 is 28. 5 times 5 is 25, plus 3 is 28, so therefore the answer is x=5
Answer:
c = 72
Step-by-step explanation:
multiply both sides of the equation by 8 to eliminate the fraction
c = 8 × 9 = 72
note that 
= 9
