8. Find the number of real number solutions for the equation. x2 – 10x + 25 = 0

A. 0
B. 1
C. 2
D. cannot be determined

B. 1

Step-by-step explanation:

Option B is correct

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

Step-by-step 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

0,0

step-by-step explanation:

the answer is $42.96
