Learn to find the zeros of a quadratic using the quadratic formula

The video tutorial explains how to solve a quadratic equation by first setting it to zero and ensuring the quadratic term is positive. It then covers identifying the coefficients (A, B, C) and calculating the discriminant to determine the nature of the solutions. The quadratic formula is applied to find the solutions, which are then simplified. The instructor also addresses common student mistakes and questions, emphasizing the importance of correctly identifying coefficients and understanding the nature of solutions.

Explain the significance of the square root in the quadratic formula.

What happens when the discriminant is positive, according to the discussion?
