Question

If the zeros of the polynomial are -2,-4,2 and 4 .then find the polynomial .​

Answer 1

Answer:

x⁴-20x²+64

Step-by-step explanation:

The polynomial is (x+2)(x-2)(x+4)(x-4)

as x+2= 0 ... x= -2

x-2 = 0 ... x = 2

x-4= 0 ... x= 4

x+4=0 ... x= -4

= (x²-4)(x²-16)

x⁴-16x²-4x²+64

=x⁴-20x²+64
