[tex]x^2+3x-5=0\\a=1;\ b=3;\ c=-5\\\\ x=\frac{-b^+_-\sqrt{b^2-4ac}}{2a}\\\\x=\frac{-3+\sqrt{3^2-4\cdot1\cdot(-5)}}{2\cdot1}\quad\vee\quad x=\frac{-3-\sqrt{3^2-4\cdot1\cdot(-5)}}{2}\\\\x=\frac{-3+\sqrt{9+20}}{2}\quad\vee\quad x=\frac{-3-\sqrt{9+20}}{2}\\\\x=\frac{-3+\sqrt{29}}{2}\quad\vee\quad x=\frac{-3-\sqrt{29}}{2} \\\\x\approx1.19\quad\vee\quad x\approx-4.19[/tex]
