Answer:
Step-by-step explanation:
Factor 4x3−16x
4x3−16x
=4x(x+2)(x−2)
Answer:
4x(x+2)(x−2)
Answer:
x= 0 x= -2 x= 2
Step-by-step explanation:
take out any common factors which in this case is x.
4x^3-16x -------> x(4x^2-16)
this turns it into a difference of squares
factor x(4x^2-16) -------> x(2x+4)(2x-4) -------> this is the factored form
to solve, set each part equal to 0
x=0 2x+4=0 2x-4=0
solve
x=0 x=-2 x=2
