Thank you for the opportunity to help you with your question!

Solving a quadratic equation in one variable, ax^2 + bx + c = 0. To solve a quadratic equation, the easiest way is to use quadratic formula. The quadratic formula is x = [-b +- square root of (b^2 - 4ac)]/2a. 

For example,

solve the quadratic equation  x^2 - 3x + 2 = 0.

x = [-(-3) +- square root(9 - 8)]/2  = (3+1)/2  or (3-1)/2  =  2 or 1.


Now solve the equation below:

x ^ 2  + 4x + 3 = 0

Please let me know if you need any clarification. I'm always happy to answer your questions.
