This is a digital matching and puzzle assembling activity on solving quadratic equations with complex solutions. In the first slide there are nine problems (quadratic equations) numbered with 1a,1b,1c,2a,2b,2c,3a,3b, and 3c. Students are asked to solve each equation by completing the square or the quadratic formula. In the second slide the answers of the problems are given in random order. Students have to type the number of each problem next to its answer in the empty box provided. There is als
