0 = 5x² + 30x-10

Faktor

 

\(0 = 5x² + 30x-10\\0=5(x^2+6x-2)\) 

.                   p         q

 

\(0=5(x-x_1)(x-x_2)\) 

 

\(x_{1,2}=-\frac{p}{2}\pm\sqrt{(\frac{p}{2})^2-q}\)

 

\(x_{1,2}=-3\pm\sqrt{9+2}\\x_1=-3+\sqrt{11}\\x_2=-3-\sqrt{11}\)

 

\(0=5(x-\sqrt{11}+3)(x+\sqrt{11}+3)\)

\(0=5(x-0.3166...)(x+6.3166...)\)

 

laugh  !
