Question

x²= 4/5x+1/5 por favor alguém responde

Answer 1

x^2= 4/5x + 1/5
x^2= (4x^-1)/5 + 1/5
(x^2)/x^-1= 4/5 + 1/5
(x^2)*(x)= 5/5
x^3= 1
$\sqrt[3]{1}$
x= 1

Answer 2

5x²/5 = 4x/5 + 1/5 5x² - 4x - 1 =0 Δ= 16 - 4.5.(-1) Δ=16+20 Δ=36 X1=_(-4)+_√36/2.5 X1=4+6/10 X1=10/10 X1=1 X2=4 - 6/10 X2= - 2/10 X2= - 1/5
