You can find the solution(s) to ANY Quadratic Equation using the. Where First a, b, and c. Plug values into the formula and simplify using of. As usual with Quadratics, be sure to a side before Identifying values. Formula Empty Order Identify Quadratic Operation

Problem 1 Using the Quadratic Formula Find the solutions of x. A. x 2 – 3x – 10 = 0 B. 3x 2 – 17x = 20 {5, –2} 3x 2 – 17x – 20 = 0 –20 1 –3 Now separate the quotients 3 –17 –10 a = b = c = Now separate the quotients

Problem 2 Finding Approximate Solutions Brian throws a baseball across the field. The arc of the ball can be modeled by the equation y = –0.05x x + 4, where x is the horizontal distance (in meters) from Brian and y is the height (in meters) of the ball at any given time. How far from Brian does the ball land? y = –0.05x x = –0.05x x + 4 – Now separate the quotients 4 a = b = c = Cannot have a negative distance The ball lands approximately 19.17m from Brian
