Which polynomial equation has the roots of -2, `-1/2` , and 5?

### 1 Answer | Add Yours

Roots mean solutions that make it true or zeroes. A possible solution would be:

`(x + 2)(x + 1/2)(x -5)`

``when multiplied gives you:

`x^3 - 5/2x^2-23/2x - 5`

which is choice a from your solutions.

`-5/2 = -2.5`

and `-23/2 = -11.5`
