Respuesta :
A) the greatest common factor is how to factors something
for this case x is the gcf
x(x^2 - 4) is the answer
B) Cannot be factored there is no common factor.
a) gcf is x
x(x^3/x - 4x/x)
x(x^2 - 4)
x(x^2 - 2^2)
x(x+2)(x-2)
b) 3t^2 -u^2
(3t+u)(3t-u)
x(x^3/x - 4x/x)
x(x^2 - 4)
x(x^2 - 2^2)
x(x+2)(x-2)
b) 3t^2 -u^2
(3t+u)(3t-u)
