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

Multiply powers with the same base : a^b * a^c = a^(b + c)....so basically, u keep the bases and add the exponents.
dividing powers with the same base : (a^b) / (a^c) = a^(b - c)....so basically, u keep the base and subtract the exponents
raising a power to a power : (a^b)^c = a^(b * c)...so basically, u multiply the exponents
