QUADRATIC EQUATION
What is the sum of roots of the quadratic equation x²-2x+5=0.
Final Answer:
A. 2
Step-by-step explanation:
x² - 2x + 5 = 0.
First, identify the value of a, b, and c.
Given:
- a = 1
- b = -2
- c = 5
Formula to be used: [tex]\: \Large \frac{ - b}{a} [/tex]
Solution:
Simply use the given formula to find the sum of the roots.
[tex]\begin{gathered} \frac{ - b}{a} \\ = \frac{ - ( - 2)}{1} \\ = \frac{2}{1} \\ = 2\end{gathered} [/tex]
Thus, 2 is the sum of the roots.
