This post explains and give practice opportunities related to TEKS A.7B:
describe the relationship between the linear factors of quadratic expressions and the zeros of their associated quadratic functions
Students learn to use the factored form [f(x) = a(x-u)(x-v)] of the quadratic function to find zeros in quadratic equations.
Between 2016 and 2023 (including redesign practice), this supporting standard has been tested 7 times on the STAAR test. Videos explaining the problems can be found below.
