Answer:
A. TRUE
Explanation:
To verify if that value 5 is a solution, you place it in the equation instead of 'x' and see if the equality is respected at the end.
The equation is: x² - 6x + 5 = 0
Now, let's replace x by 5:
5² - 6 (5) + 5 = 0
25 - 30 + 5 = 0
-5 + 5 = 0
0 = 0
Since 0 = 0 is true, the value 5 is a valid solution for this equation.
If we had tried with 6, it would have ended with
36 - 36 + 5 = 0
5 = 0
So, 6 is NOT a solution.
