Determine all the zeros of p(x)=x^4-9x^2+20

ANSWER

Real roots

x=5

x=7

Complex roots

x=2+3–√i≈2.0+1.73205080756888i

x=2−3–√i≈2.0−1.73205080756888i

Step-by-step explanation:

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

where are the choices?
