Question

X .(2x+1)=5x qual é a resposta

Answer 1

x.(2x + 1) = 5x
2x² + x = 5x
2x² + x - 5x = 0
2x² - 4x = 0
x.(2x - 4) = 0
x = 0

2x - 4 = 0
2x = 4
x = 4/2
x =  2

R.: x = 0 e x = 2

*************************************

Answer 2

x.(2x+1)=5x
2x^2+x=5x
2x^2+x-5x=0
2x^2-4x=0
2x*(x-2)=0
logo x=0 e x=2
