solve for x

4x+-8000x^-2=0

4x(1-2000x)= 2

4x= 2 or 1-2000x= 2

x= 1/2 or x= -1/2000

best me please

where did the 2 come from? when you factored

i took the -2 to the other side of the equition

that is x to the power of -2

oooh sorry

it should be this way

4x- 1/8000^2=0

4x= 1/8000x^2

32000x^3= 1

x= the cube root of 32000

x is approximately 536

wouldnt it be the cube root of 1/3200 ?
