Question

What are the zeros of the function f(x) = x2 + 5x + 5 written in simplest radical form? Quadratic formula: x =

Answer 1

To solve this problem you must apply the proccedure shown below:
 1. You have the following quadratc equation given in thte problem above:
 $f(x) = x^2 + 5x + 5$
 2. To solve it, you must apply the quadratic formula, which is:
 $x=( -b+ \sqrt{ b^{2}-4ac }) \ /2a$
 3. When you substitute the values into the quadratic formula, you obtain that the answer is:
 $x1=( \sqrt{5} -5)/2 \\ x2=( -\sqrt{5} -5)/2$
