Document Summary
A quadratic equation is an equation of the form ax2 + bx + c = 0 where a, b, and c are real numbers and a 0. When it is written in this form, it is said to be in standard form. A quadratic equation is called a second degree equation. Zero-product property: if a product which is factored equals zero then at least one of the factors of the product is equal to zero. Factoring: the quadratic must be in standard form first, then factor the quadratic and set each factor equal to zero and solve. Square root method: the quadratic must be in the form something squared equals a number, u2 = p, where u is some expression with a variable, and p is a number. To solve a quadratic of this type, you take the square root of both sides to obtain u.
