Question 256419
What is the Quadratic Formula Answer to this: 
If the quadratic formula is used to solve 2x(x + 5) = 4, what are the solutions?
------------------
The solutions are the same, regardless of what method is used.  There is no "Quadratic Formula Answer", only an answer, or solution(s).
----------------
2x(x + 5) = 4
x(x + 5) - 2 = 0
{{{x^2 + 5x - 2 = 0}}}
