Answer:

B. 1

Explanation:

Answer:

Option B is correct

The number of real number solutions for the given equation is, 1.

Explanation:

Given the equation:

Since, this is a quadratic equation of the form of

where a =1 , b = -10 and c =25.

The discriminant of a quadratic equation is,

then;

Discriminant = = (100-100) = 0

Since, a discriminant of zero means there is only one real solution for x.

Substitute the given values.

Simplify:

x = 5

Therefore, the number of real solution for the given equation is, 1
