Given the expression:

$\text{ (x + 25)}^2$

Let's expand the expression into a perfect square trinomial.

$ax^2\text{ + bx + c}$

We get,

$\text{ (x + 25)}^2$
$(x)(x)\text{ + (25)(x) + (x)(25) + (25)(25)}$

$\text{ x}^2\text{ + 25x + 25x + 625}$
$\text{ x}^2\text{ + 50x + 625}$

Since the c-value in the perfect square trinomial is the constant in the equation, therefore, the c-value is 625.
