WebThere are four sets of cards. Each set of cards uses a different technique for solving quadratic equations. Three sets use a specific technique: factoring, completing the square, and the square root property. The fourth set is mixed practice, including the quadratic formula. Equations with complex solutions are not included. Each set has 15 cards. WebSolve by completing the square: Non-integer solutions. Worked example: completing the square (leading coefficient ≠ 1) Solving quadratics by completing the square: no solution. Proof of the quadratic formula. Solving quadratics by completing the square. Completing the square review. Quadratic formula proof review. WebSummary. Quadratic Equation in Standard Form: ax 2 + bx + c = 0. Quadratic Equations can be factored. Quadratic Formula: x = −b ± √ (b2 − 4ac) 2a. When the Discriminant ( b2−4ac) is: positive, there are 2 real solutions. zero, there is one real solution. negative, there are 2 complex solutions. bitter bark in tonic water
