The values are a=1 b=10 c=25 and solving the expression we get x=-5

Explanation:

Given equation; $x^{2}+10 x+25$

Solution:

The above equation can be written as $x^{2}+10 x+25=0$

This equation is in the form of $A x^{2}+B x+C=0$

$A x^{2}+B x+C=0$ is the general quadratic equation.

Comparing the above equation we get

A=1, B=10 and C=25

To find value of “x” we use the formula as

= $\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$

Substitute the values of a, b and c in the above equation we get

= $\frac{-(10) \pm \sqrt{10^{2}-4(1)(25)}}{2(1)}$

= $\frac{-(10) \pm \sqrt{100-4(1)(25)}}{2}$

= $\frac{-(10) \pm \sqrt{100-100}}{2}$

= $\frac{-10}{2}$

=-5

Results:

Thus the values are A=1, B=10, C=25 and X=-5
