Answer 2

Answer :- The value of a is 18

Step by Step Explanation :-

Given :- 3 is a zero of p (x) → 4x² - ax + a

✔This implies that if we put x = 3 in the equation , the result must be equal to zero.

→so let's put x = 3

→4 (3)² - 3a + a = 0

=4 × 9 - 2a = 0

=36 - 2a = 0

=36 = 2a

★a = 18

The value of a is 18!
