Question

$\frac{4}{7} x ^{2} = 0$
Me ajudemmmmmm pfvr ​

Answer 1

Delta = 0

x1 = 0 + 0 / 2.(4/7)

x2 = 0 - 0 / 2.(4/7)

x = 0

S = {0}

Answer 2

Explicação passo-a-passo:

$\sf \dfrac{4x^2}{7}=0$

$\sf 4x^2=7\cdot0$

$\sf 4x^2=0$

$\sf x^2=\dfrac{0}{4}$

$\sf x^2=0$

$\sf x=\pm\sqrt{0}$

$\sf \red{x'=x"=0}$

$\sf S=\{0\}$
