Answer 1

There's only one solution which is for \(x\) to be zero.

Answer 2

In this case you can simply figure it out by inspection. Just try to plug in values as x to get zero as a result. As the term is a product there's only zero a possible answer

Answer 3

The number of solutions of an equation the exponent of the leading term.
In this case the bigget exponent is 2, so the number of solutions is 2

Answer 4

o counts as a "double root"
