Step-by-step explanation:
Hello,
First of all, let's notice that even if we do not know the zeros of P(x) we can say that
<u>But, why !?</u>
As they are the zeros of P(x), we can write:
And then we can identify the coefficients of the like terms to find the equations (1) and (2).
Now, we have <u>one more equation</u> which is:
(1)+(3) gives:
And we replace in (3) to get the value of the second zero.
And, finally, from (2), it comes:
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
