my vote is ispy
0=5x2+30x-10
factor
+15001 0 = 5x² + 30x-10
Faktor
\(0 = 5x² + 30x-10\\0=5(x^2+6x-2)\)
. p q
\(0=5(x-x_1)(x-x_2)\)
\(x_{1,2}=-\frac{p}{2}\pm\sqrt{(\frac{p}{2})^2-q}\)
\(x_{1,2}=-3\pm\sqrt{9+2}\\x_1=-3+\sqrt{11}\\x_2=-3-\sqrt{11}\)
\(0=5(x-\sqrt{11}+3)(x+\sqrt{11}+3)\)
\(0=5(x-0.3166...)(x+6.3166...)\)
