Abstract: The research objective is to determine the effectiveness of the X-Box Method in factoring quadratic trinomials. The participants were 100 Mandurriao National High School grade 8 students divided into control and experimental groups. The respondent in each group is matched according to their pretest result. The control group in the study used the sum and product method, whereas the experimental group utilised the X-Box method. The data collected were analysed with the aid of SPSS. Specifically, the mean, standard deviation, dependent-samples T-test, and Independent-samples T-test were employed. The results revealed that learners’ performance was below average before the intervention, and both interventions helped improve students’ performance. Compared to the sum and product method, the X-Box method improved. Suggesting that the X-Box method may be particularly beneficial for learning. However, there is no significant difference in the post-test results of both methods.
