Oh what a relief that somebody taught this on YouTube! I never learned how to do this type of math problem ever!

Hello from France everyone!
There is a shorter way in two steps.
Step 1: calculate the discriminant (b^2 - 4ac). A rule says that when the discriminant is 0, there is only one solution (with a multiplicity of 2) which is : (step 2) x = -b / 2a.
