Question

find the number to be added to be polynomial x2 - 5 x + 4 so that 3 is the Zero polynomial​

Answer 1

Answer:

Step-by-step explanation:

x = 3

=> (3)²-5(3)+4

=> 9 - 15 + 4

=> -2

2 must be added.

Check....(3)²-5(3)+4+2

=> 9 - 15 + 4 + 2

=> 15 - 15

=> 0

Thus, 3 becomes zero of the above given polynomial upon adding 2.
