Question

Hey dear friends please help me solving this question​

Answer 1

Answer:

5

Step-by-step explanation:

Given polynomials:

3x² - px + 2

4x² - qx - 10

Given zero of the polynomials = 2

So, x = 2

Substituting this value of x in both the polynomials, we get

3 (2)² - p (2) + 2 = 0 ————1

12 - 2p + 2 = 0

-2p = -14

p = 7

4 (2)² - q (2) - 10 = 0 ————2

16 - 2q - 10 = 0

-2q = -6

q = 3

Therefore, 2p - 3q = 2 (7) - 3 (3) = 14 - 9 = 5
