# Equations that simplfy to Quadratics Watch

1. Find all four soloutions of the equation x^4 -(6root2)x^2 +24 =0

So i let p =x^2 so we get x^2 -(6root2)x +24 =0

then when i plug this into the quadratic formula and divide through by 2 i get the wrong answer... Answer is +-1.86 +-2.63

if you let p=x^2, then when you have found p, x=+-sqroot(p)
