Consider the trinomial 
1. Find the discriminant:

2. Find the roots of given trinomial:

3. Conclusion: given trinomial has two different real roots.
Answer:
x=2c/3+1
Step-by-step explanation:
Subtract 2c from both sides.
−3x=−3−2c
The equation is in standard form.
−3x=−2c−3
Divide both sides by −3.
-3x/-3=-2c-3/-3
Dividing by −3 undoes the multiplication by −3.
x=-2c-3/-3
Divide −3−2c by −3.
x=2c/3+1
Your answer is A. Megan is correct. When two lines have different slopes, they must intersect, producing one solution.
