The difference of two squares is often used to factorize expressions involving quadratics.
In particular quadratic equations looking like:
\[x^2-k^2 = 0\]
In the following tutorial we learn how to use the difference of two squares to factorize quadratics.
Write each of the following quadratics in factored form:
Using the method we can solve any quadratic equation of the type:
\[x^2 - k = 0\]
For instance, we can solve \(x^2 - 16 = 0\), or eve
The null factor law states:
Given a quadratic equation of the type \(x^2 - k = 0\), we can solve this in two steps:
In the following tutorial we review the ... .
Use factorization to solve each of the following quadratic equations:
