I can easily factor with the x method and when all positive and a does not equal 0 I can do it perfectly fine. My problem occurs when it is a negative in the quadratic function. I just don't know...
The Quadratic Formula The quadratic formula is a fundamental formula used to find the roots of quadratic equations. Roots of quadratic polynomials are defined as the values of the variables for which the quadratic polynomial is equal to zero. For example, given the general form of a quadratic polynomial the roots of the above are defined as the values of x for which the above... read more
