blackpenredpen | I derived the quadratic formula while blindfolded @blackpenredpen | Uploaded 3 years ago | Updated 28 seconds ago
We will derive the quadratic formula while blindfolded. The quadratic formula is a powerful method of solving ANY quadratic equations, especially when the quadratic equations are not factorable. The secret is to start with ax^2+bx+c=0 and multiply every term by 4a. This is a much easier way to prove the quadratic formula, which is used for solving quadratic equations.
