Sagot :

[tex]5x^{2} + 11x = 0 [/tex]
[tex]5x^{2} + 11x + 0 = 0[/tex]
[tex]x = \frac{-(11) +/- \sqrt{(11)^{2} - 4(5)(0)}}{2(5)} [/tex]

[tex]x = \frac{-11 +/- \sqrt{121 - 0}}{10} [/tex]

[tex]x = \frac{-11 +/- \sqrt{121}}{10} [/tex]

[tex]x = \frac{-11 +/- 11}{10} [/tex]

[tex]x = \frac{11 + 11}{10} [/tex]         [tex]x = \frac{11 - 11}{10} [/tex]

[tex]x = \frac{22}{10} [/tex]               [tex]x = \frac{0}{10} [/tex]

[tex]x = 2.2[/tex]              [tex]x = 0[/tex]
