Thank you for your help :)
1 answer:
Factor
remember
if xy=0, assume that x and y=0
also
difference of 2 perfect squares
a²-b²=(a-b)(a+b)
so
5x³-5x=0
factor out 5x
5x(x²-1)=0
5x(x²-1²)=0
factor perefect square
5x(x-1)(x+1)=0
set each to zero
5x=0
x=0
x-1=0
x=1
x+1=0
x=-1
x=-1 or 0 or 1

Answer:

= 56n - 35
