Question

Find the values of
Write the zeros of the polynomial p(x) = x2 - x - 30.

Answer 1

Step-by-step explanation:

Consider the provided polynomial.



Let 

Substitute p(x)=0 and split the middle term.









Thus, the zeros of the quadratic polynomial is -5 and 6.

Verify:





Which is true.





Which is true.

Answer 2

1. The sum of the roots of the equation ax
2. 2+bx+c=0 is − ab
4. And product of the roots is ac
6. Here one of the roots is 1. Let the other be p
7. Sum of the roots=1+p=1⇒ p=0
8. Product of the roots=p×1=k⇒ k=0
9. Therefore, Option B is correct
