TI 84 Parabola Solver: PARA will help you solve all the questions asked about parabolas in your math class. Just enter the coefficients of the Ax-squared + BX + C of your parabola in standard form and your PARA program will solve everything for you. A is your x-squared coefficient (often it’s 1); B is your x-coefficient; C is your constant, otherwise known as number. In the first example in the video, since there is no stated x-squared coefficient, it is 1. The x-coefficient is 5 (your B value) and your constant/number is 6 (your C value).
