Question

If a and B are zeros of polynomial p(x) = x²- 5x + 6, then find the value of
i) 1/a²+1/ß²​

Answer 1

Answer:

13/36

Step-by-step explanation:

x² - 5x + 6 = 0

(x-3)(x-2) = 0

So,

A = 3

B = 2

E = 1/A² + 1/B² = 1/3² + 1/2² = 1/9 + 1/4 = 13/36

Answer 2

Answer:

13/36

Step-by-step explanation:

Factorizing equation we get

(x-2)(x-3) = 0

So, roots are 2 and 3

Putting the value

1/2²+1/3²

1/4 +1/9

On solving this we will get 13/36
