Ix-2I/3<4

time 3 both sides

Ix-2I < 12

a million. Subtract 4x^2 from the two facets x^4-4x^2+3=0 2. Say that y =x^2, and replace that fee interior the equation (x^2)^2-4(x^2)+3=0 y^2-4y+3=0 3. resolve like familiar quadratic (y-a million)(y-3) 4. resolve for the two y values y=a million y=3 5. If y=^2, then x=sqrt(a million) x=sqrt(3)
