BUSI 1915U Lecture Notes - Lecture 6: Quadratic Formula, Greatest Common Divisor, Quadratic Equation
Document Summary
A quadratic equation is an equation of the form ax2 + bx + c = 0, where a, b, and c are real numbers with a 0. Factoring is the process of expressing an algebraic expression as a product of other algebraic expressions. Check to see whether any of its terms have common factors. If they do, then factor out the greatest common factor. Certain product formulas that are useful in factoring. Given px2 + qx + r and p 1, then you need find two numbers that multiply to equal the product of constant terms p and r and add up to equal the term q. Important: you need to remove all common factors before you use this procedure. Many quadratic equations can be factored and if one side of the equation is a product and the other side is 0, we can write an equivalent statement by setting each factor equal to zero.
