Question

X 3 (x 2 −5)=−4xspace, x, start superscript, 3, end superscript, left parenthesis, x, start superscript, 2, end superscript, minus, 5, right parenthesis, equals, minus, 4, x if x > 0x>0x, is greater than, 0, what is one possible solution to the equation above?

Answer 1

One possible solution is x=1 or x=2

Explanation:

we have

`x^(3)(x^(2)-5)=-4x`

For x> o

using a graphing tool

The solutions are x=-2,x=-1,x=0,x=1,x=2

see the attached figure

therefore

One possible solution is x=1 or x=2
