Question

Use the quadratic formula to solve the equation. Show all work. (No decimal answers)

Answer 1

Answer:

$x_{1} =2$

$x_{2} =4/5$

Step-by-step explanation:

$a=5, b=-14, c=8$

$x=\frac{-(-14)+-\sqrt{(-14)^{2}-4(5)(8) } }{2(5)}$

$x=\frac{14+-\sqrt{196-160} }{10}$

$x=\frac{14+-\sqrt{36} }{10} =\frac{14+-6}{10}$

$x_{1} =\frac{14+6}{10} =\frac{20}{10} =2$

$x_{2} =\frac{14-6}{10} =\frac{8}{10} =\frac{4}{5}$
hope this helps
