X2 - 10x + 25

Upper x

To solve the quadratic function shown above, you can factor it, as following:

x^ 2-10x+25=0

(x-5) (x-5) = 0

Then, you can rewrite the expression (x-5) (x-5) = 0 as

(x-5) ^2=0

When you solve it, you obtain that the value of the variable x is:

x=5

Therefore, the answer is: x=5
