The discriminant = 0
Explanation:The given equation is:
[tex]x^2-10x+25=0[/tex]Compare x² - 10x + 25 = 0 with ax² + bx + c = 0
a = 1, b = -10, c = 25
The discriminant is given by the formula:
[tex]D=b^2-4ac[/tex]Substitute a = 1, b = -10, c = 25 into the discriminant formula above
[tex]\begin{gathered} D=(-10)^2-4(1)(25) \\ D=100-100 \\ D=0 \end{gathered}[/tex]The discriminant = 0
