Abstract	This study showed the effectiveness of solving quadratic equations by completing the square: with and without strategic intervention material (WAW SIM). The purpose of this study is to be able to enhance the skills, knowledge and make lessons more exciting for students to learn. Thirty (30) students were used as experimental and control groups, to identify the effectiveness in solving quadratic equations by completing the square the difference of mean percentage scores of pre-assessment and post-assessment of both groups was used. However, to verify if there is a significant difference between the two groups, the t-test will be performed at a 0.05 level of significance. Based on the conclusion, the variable Without SIM there was a significant difference in performance in their pre-assessment and post-assessment having a slightly higher t-test result of 9.15 than the critical value of 2.045. And it was shown from their Mean Percentage Score (MPS) that the result in post-assessment was slightly higher from 41.7% to 62%. A little increased learning but it is not an effective way of solving quadratic equations by completing the square. While the variable With SIM there was a significant difference in performance in their pre-assessment and post-assessment having a greater t-test result of 23.99 than the critical value of 2.045. And it was shown from their Mean Percentage Score (MPS) that the result in post-assessment was more than doubled from 41.7% to 89% it’s a greater increase in learning and a very effective way of solving quadratic equations by completing the square.
