Question

find all zeros of f(x) equal xcube minus 2x​

Answer 1

f(x)=x^3-2x

f(x)=x(x^2-2)

x=0,x^2-2=0

x=0,x^2=2

x=0.x=root2.

Hence,the zeroes of f(x) are 0 and root2.

Answer 2

Answer:

for finding zero,

p(x)=0

=> x³-2x=0

=> x(x²-2)=0

=> x=0 and x²-2=0

=> x=0 and x= √2,-√2

so, x=0,√2,-√2.
