Question

How many roots does the equation -2x3 = 0 have?

Answer 1

The equation is \(-2x^3 = 0\) correct?

Answer 2

@ hero yes

Answer 3

And if we divide both sides by -2 what do we get?

Answer 4

0

Answer 5

So you get \(x^3 = 0\). So what is the next step?

Answer 6

To CUBE ROOT both sides correct. What does CUBE ROOT imply?

Answer 7

If there was only one solution, what need would there be to cube root?

Answer 8

If you have \(x^n= a\) and apply \(\sqrt[n]{\phantom{x}}\) to both sides, to get \(x = \sqrt[n]{a}\) this implies that \(x\) has \(n\) solutions.

Answer 9

@yungtwan did you get this?
