Плз (3x+1)(6-4x)=0 и (6x+3)(9-x)=0 заранее спасибо ☺️
(3x + 1)(6 - 4x) = 0 3x+ 1= 0 3x = - 1 x = - 1/3 6 - 4x = 0 - 4x = - 6 4x =6 x = 6/4 = 3/2 = 1,5 ========================================== (6x + 3)(9 - x) = 0 6x + 3 = 0 6x = - 3 x = - 3/6 = - 1/2 = - 0,5 9 - x = 0 - x = - 9 x = 9
Спасибо большое!!!
