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
We use the FOIL method here. First, Outer, Inner, and Last.
(5x)(x) = 5x^2
(5x)(-7) = -35x
(2)(x) = 2x
(2)(-7) = -14
5x^2 - 35x + 2x - 14
Now combine like terms.
5x^2 - 33x - 14.
This is the right answer because it is now in the form of ax^2 + bx + c
Factor out 18.
The factors for 18 are as listed:
1, 2, 3, 6, 9, 18
Now factor out 30.
The factors for 30 are as listed:
1, 2, 3, 5, 6, 10, 15, 30
Now look at the factors that are both factors for 18 and 30.
So, the common factors are 2, 3, and 6.
