Question

The number that must be added to x^2-3x^2-12x+19 so that 2 is zero of the polynomial

Answer 1

Answer:

Step-by-step explanation:

x = 2

=> (2)²-3(2)²-12(2)+19

=> 4 - 12 - 24 + 19

=> -13

13 must be added.

Check.....(2)²-3(2)²-12(2)+19+13

=> 4-12-24+32

=> 36-36

=> 0

Thus, 2 becomes zero of above given polynomial upon adding 13.
