Lesson 1.1: QUADRATIC EQUATIONS Quadratic equations are expressions where the highest degree of any variable is 2. Standard form of quadratic equations: ax + bx + c = 0 2 where: ax - Quadratic term 2 bx - Linear term c - Constant a, b, and c are real numbers, and a ≠ 0. Example 1: 5x + 3x + 1 = 0 2 Quadratic term - 5x 2 Linear term - 3x Constant - 1 As long as the highest degree of a variable is two, it is still classified as a quadratic equation. If the linear or constant term is missing, then it is an incomplete quadratic equation. Example 2: 3y - 5y = 0 (No constant term) 2 u - 169 = 0 (No linear term) 2 k = 0 (No linear and constant term) 2 In Disguise Quadratics cannot be easily identified as a quadratic equation. Example 3: (y-3)(y+2)=0 By FOIL method: = y +2y-3y-6 2 0 = y -y-6 2 (wow, may quadratic pala!)
