x 2 +25=10x+4

Sure, let's solve the equation step by step:

1. First, let's rewrite the equation to bring all terms to one side: x^2 - 10x + 25 - 4 = 0
2. This simplifies to: x^2 - 10x + 21 = 0
3. Now, we can factor the quadratic equation: (x - 7)(x - 3) = 0
4. Setting each factor equal to zero gives the solutions: x = 7 and x = 3.
