I am creating a self-checking assignment for Algebra I where students need to find the roots/solutions of a quadratic given in standard form. Does anyone know how to allow two possible answers in a math input (so that a student could enter either intercept and be correct)? Also, how can I enter a fraction as the correct answer?

See slide 9 in the activity: https://teacher.desmos.com/activitybuilder/custom/5ffb18921488571bf77e729d

Thanks!
