5x^2+11x=0 quadratic equation

Mathematics
1 answer:
hammer [34]3 years ago
3 0
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

Answer:

  x = 14°

Step-by-step explanation:

  C = 180° -124° = 56°

The exterior angle at B is the sum of the remote interior angles:

  6x = 56° +2x

  4x = 56° . . . . . . subtract 2x

  x = 14° . . . . . . . . divide by 4
