Solve each equation using the quadratic formula. Find the exact solution, then approximate the solution to the nearest hundredth

Mariana [72]

Answer:

$n_1=2.72\\n_2=0.61$

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

1. You have that the quadratic formula is:

$x=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}$

2. To solve the quadratic equation you must substitute the values. So, you have that:

$a=3\\b=-10\\c=5$

Then you have:

$x=\frac{-(-10)+/-\sqrt{(-10)^{2}-4(3)(5)}}{2(3)}$

3. Therefore, you obtain the following result:

$x_1=2.72\\x_2=0.61$
