Asking someone for help with a math problem and asking someone to solve your math problem are not the same thing.
If you want help, then you need to show your work so the helpers here know what type of help you need.
Since you did not show any work then I can only assume that you do not know where to start.
Here is a hint: If x=a make a polynomial equal to 0, then (x-a) must be ONE of the factors of the polynomial (for the record, x-a can be the only factor of the polynomial).
Can you respond with some work from that hint? If not, then please respond saying that.
