Question: Hi! Use the most appropriate method to determine the zeros of the function y= -5(x+1)(x-4) - How many real roots are there for the given

Hi!

Use the most appropriate method to determine the zeros of the function

y= -5(x+1)(x-4)

- How many real roots are there for the given function 2 or 3?

- Does the real root and number of zeros mean the same?

For example, if there are 2 real roots then does that mean there are total 2 zeros of the function?

- Is zero a real root?

I am little confused for this question but want to clear my concept. It would be great if you can provide me the explanation. Thanks for helping!
