Question

find the zeroes of polynomial z³-16Z​

Answer 1

Answer:

Hope my answer helps you mate :-)

Step-by-step explanation:

Zero of a polynomial is the value of that variable for which whole polynomial is 0

so put z³-16z=0

Take z as common

z(z²-16)=0

z×(z+4)(z-4)=0. [by identity a²-b²=(a+b)(a-b) ]

So z=0 or ±6. ± represent -or+
