[tex]\sf \longmapsto \: x^4 + 3x^2 - 4 = 0[/tex]

  • Factor left side of equation

[tex]\sf \longmapsto(x+1)(x−1)(x^2+4)=0[/tex]

  • Set factors equal to 0

[tex]\sf \longmapsto \: x+1=0 or x−1=0  \: or \:  x {}^{2} +4=0[/tex]

  • We have two possible solutions

[tex]\sf \longmapsto \: x = - 1[/tex]

OR

[tex]\sf \longmapsto \: x = 1[/tex]
