There are two <em>real</em> roots for the <em>quadratic</em> equation x² - 8 · x + 13 = 0, contained in the number x = 4 ± √2.
<h3>How to find the roots of a polynomial by completing the square</h3>
In this question we must apply algebraic handling to simplify a <em>quadratic</em> equation and find the roots that satisfy the expression. Completing the square consists in transforming part of the equation into a <em>perfect square</em> trinomial, and then we clear for x:
x² - 8 · x + 13 = 0
x² - 8 · x + 16 = 3
(x - 4)² = 3
x - 4 = ± √2
x = 4 ± √2
There are two <em>real</em> roots for the <em>quadratic</em> equation x² - 8 · x + 13 = 0, contained in the number x = 4 ± √2.
