Answer:
The equation showing this situation is
Step-by-step explanation:
Given : A quadratic equation of the form has one real number solution.
To find : Which could be the equation?
Solution :
A quadratic equation in form has a solution
called a quadratic formula in which the roots are one real,two real or no real is determine by discriminant factor.
Discriminant is defined as to determine the number of roots in a quadratic equitation has following rules :
1) If there are two real roots.
2) If there are one real roots.
3) If there are no real roots.
According to question,
A quadratic equation of the form has one real number solution.
So, The equation showing this situation is
domain is the numbes you are allowed to use for x
what I usually do is just find the numbers that aren't allowed in the domain. such numbers are numbers that cause a division by 0 or a squaer root of a negative number
given , there are no numbers that you can use for x that will cause a division by 0 or a square root of a negative number
so domain is all real numbers or D={x | -∞<x<∞}
