Question

5x^2+11x=0 quadratic equation

Answer 1

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

$x = \frac{-11 +/- \sqrt{121 - 0}}{10}$

$x = \frac{-11 +/- \sqrt{121}}{10}$

$x = \frac{-11 +/- 11}{10}$

$x = \frac{11 + 11}{10}$         $x = \frac{11 - 11}{10}$

$x = \frac{22}{10}$               $x = \frac{0}{10}$

$x = 2.2$              $x = 0$
