Question

Rezolva ecuatia de gradul 2:
$\frac{4}{49} x^{2} +1 \frac{5}{7}x +9=0$
Ofer coroana..Daka se poate rezolvarea pe foie si trimitetimi poza.♥Mersi anticipat..♥

Answer 1

$\frac{4}{49} x^{2} + \frac{12}{7} x+9=0 Δ= ( \frac{12}{7} )^{2} -(4*9* \frac{4}{49} )= \frac{144}{49} -\frac{144}{49} =0$
