Answer:
GCF = 3
Factor = 3(x^2-100)=0
Solutions are: x = 10, -10
Step-by-step explanation:
You have to factor out GCF which is 3 which then makes the equation 3(x^2-100)=0. After that you basically have (x^2-100)=0. Which then you solve for x which is a difference of squares and the answers are 10 and -10 for x.
