Can't get enough of Sal factoring simple quadratics? Here's a handful of examples just for you!
The zero product property states that if a⋅b=0 then either a or b equal zero. This basic property helps us solve equations like (x+2)(x-5)=0.
Select the graph that best suits a polynomial equation by considering the zeros of the polynomial.
Given a quadratic function that models a relationship, we can rewrite the function to reveal certain properties of the relationship. Factored form helps us identify the x-intercepts or zeros of the function. Created by Sal Khan.
