Step-by-step explanation

Answer

.....

Answer 2

AnsWer :

- 1 / 4.

Correct QuestioN :

If α and β are the zero of the quardiatic polynomial x² - x - 4. Find the value of 1/α + 1/ β

SolutioN :

Let,

• Both zeros be α and β.

★ Sum of Zeros :

↣ α + β = - b/ a.

↣ 1 / 1.

↣ 1.

★ Product of Zeros.

↣ α * β = c / a.

↣ - 4.

$\rule{80}1$

Now, Let Find.

↣ 1/α + 1/ β = α + β / α * β

↣ - 1 / 4.

Therefore, the value required is - 1/ 4.
