From the equation
{x}^{2}  - 10x + 25 = 0
We can see that 25 is 5 × 5, and 10 is 5 + 5, so the equation simplifies to
(x - 5)(x - 5) = 0 \\  {(x - 5)}^{2}  = 0
which then we use to set each parentheses to equal 0
(x - 5) = 0 \\ x = 5
Since both parentheses are the same, there is only one solution: C. 1 real number solution
