Its distributive property which states that
Option A
Answer:
Please see below.
Step-by-step explanation:
f(x) is a quadratic polynomial. Its two roots are given: x=2, and x=4.
This means that
with d some unknown constant that stretches the parabola along the y axis. Since we are also given f(1), d can be determined:
The greatest common factor is 4
