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

#SPJ1
Answer:
Step-by-step explanation:
Take the sum of each answer and add the two digits together.
9.2=18 1+8=9
9.3=27 2+7=9
9.4=36. 3+6=9
The sum of the digits added together will always equal 9
A formula is recursive if it expresses the term
in terms of the previous one(s) 
In this case, every term is 7 more than the previous one, so the formula for
will only involve
:

In fact, this formula is simply saying: for every index
, the term with that index is 7 more than the term before.
Also, we have to specify the starting point (otherwise we would go backwards indefinitely), so the complete recursive formula is

which means: start with 2 and generate every other term by adding 7 to the previous one.
Answer: 0.65 Liters
Steps:
Divide 2.6/4 to get 0.65 Liters
X^2 + 2x = -1......take half of ur x term (2x), and square it. So we take half of 2, which is 1, and square it....1^2 = 1....so u would add 1 to both sides
