Question

la solucion de la ecuacion 2/3x =2x+2 es

Answer 1

2/3X = 2X + 2

2 = 3X(2X + 2)

2 = 6X² + 6X

6X² + 6X - 2 = 0:  Donde:  a = 6;  b = 6;  c = -2

$X=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

$X=\frac{-6\pm \sqrt{6^2-4(6)(-2)}}{2(6)}$

$X=\frac{-6\pm \sqrt{84}}{12}$

X1=\frac{-6\ + \sqrt{84}}{12} = 0.2637

$X2=\frac{-6\ - \sqrt{84}}{12}$ = -1.2637
