Question

What should be added to the polynomial x²-16x+30 so that 15 is the zero of the resulting polynomial

Answer 1

Answer:

As 15 is the zero we put x=15, Which means 15 should be subtracted from p(x) so that 15 is the zero of the resulting polynomial. Therefore, The required number is 15

Answer 2

Answer:

As 15 is the zero we put x=15, Which means 15 should be subtracted from p(x) so that 15 is the zero of the resulting polynomial. Therefore, The required number is 15.
