standard_description: Know and apply the Remainder Theorem: For a polynomial p(x) and a number a, the remainder on division by x – a is p(a), so p(a) = 0 if and only if (x – a) is a factor of p(x).
problem_activity: Find the roots by factoring each of the following quadratic equations.
Additionally, for each equation, identify:
If the function has symmetry around the
y
-axis
If the root is a double root and the same as the vertex
The
y
-intercept
The vertex
a.
