Question

решите подробно ур-ие (^- степень)
4x^4-x^2=0

Answer 1

4x^4 - x^2 = 0
x^2 (4x^2 - 1) = 0

x^2 = 0
x = 0

4x^2 - 1 = 0
4x^2 = 1
x^2 = 1/4
x = ± √ (1/4)
x = ± 1/2

ОТВЕТ
- 1/2; 0; 1/2 

Answer 2

$4x^4-x^2=0\\ x^2(4x^2-1)=0\\ x^2=0\\ 4x^2 - 1 = 0\\ 4x^2 = 1\\ x^2 =frac{1}{2}\\ x_1=-frac{1}{2} \\ x_2=0\\ x_3=frac{1}{2}$
