Question

The number of solutions of (x2 + 1)2 + 2(x2 + 1) - 3 = 0 is equal to

A. 1
B. 2
C. 3
D. 4

Answer 1

I'm pretty sure it's 3. I say that because I get 3 different answers.

x = -1 / 8

x = -0.125

x = -2^3

Those are the answers I got to solve the equation. There also is an answer if I were to rewrite the equation which is... 8x = -1

I hope this helps in any way <3
