Question

4x^4=12x^2

Answer 1

??

Answer 2

i need to find the roots idk wtf im doing im so stuck on this stupid test :'(

Answer 3

4x^4-12x^2=0
now let's put x^2=t, so x^4=t^2
so the equation becomes: 4t^2 -12t=0
solving: 4t(t-3)=0 t=0 and t=3
for t=0 :
x^2=0 x=0 double root
for t=3:
x^2=3 x=+-sqrt 3
