Solve for x^4 - 17x^2 + 16 = 0 Select all possible solitions

Step-by-step explanation:

4-17x^2+16=0 s

Calculate multiply

20-17x^2=0

Reoder the term

-17x^2+20=0

Calculate the discriminat

D=0^2-4x(-17)x20

Simplify

D=1360

The quadric equation has 2 real solutions

So your Solution is :

2 real solutions

it is contrapositive
