Question

rezolvati in R ecuatia 1\2x+1 -3\2x^2+x=4\x

Answer 1

1\2x+1 - 3\2x*2 + = 4\x
8x = 1\1 -3\2 = 4
8x = 4- ( 1\1 - 3\2) --- ridicam la putere prima fractie  la 4 si a doua la 2
8x = 4- ( 4\4 - 6\4 )
8x = 4 - ( 1 - 6\4 )
8x = 4 - 1 6\4
8x = 3 4\4 - 1 6\4 -----adaogam o unitate la numaratorul primei fracti
8x = 2 0\8 = 2,4
x = 2,4 : 8 
x= 0,3
