What are the solutions of 4x^4 – 4x^2 = 8? x = ± i x = ±1 x= ± sqrt 2 x= ±2

Yo need asap pls ! markin da brainiest too !

Rewrite 9 log, x2 in a form that does not use exponents. 9log, x = log, x

Scenario: susan wants to make 2 square flags to sell at a crafts fair. the fabric she wants to buy is 3 meters wide. she doesn't want any fabric left over. what's the least amount of fabric she should buy? question: which equation will susan solve her problem? note: let x represent the length of 1 side of the flag. options: 1) 2x^2 = 4x 2) 8 +2x = 2(4x) 3) 2 * 2 = 4 * 2 4) 4x^2 -2x = 0
