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

Pavel [41]

$\boxed{x_{1}=\frac{-5 + \sqrt{5}}{2}} \\ \\ \\ \boxed{x_{2}=\frac{-5 - \sqrt{5}}{2}}$

<h2>Explanation:</h2>

Using the quadratic formula:

$x=\frac{-b \pm \sqrt{b^2-4ac}}{2a} \\ \\ \\ Here: \\ \\ f(x) = x^2 + 5x + 5 \\ \\ \\ So: \\ \\ a=1 \\ \\ b=5 \\ \\ c=5 \\ \\ \\ x=\frac{-5 \pm \sqrt{5^2-4(1)(5)}}{2(1)} \\ \\ x=\frac{-5 \pm \sqrt{25-20}}{2} \\ \\ x=\frac{-5 \pm \sqrt{5}}{2} \\ \\ \\ Two \ solutions: \\ \\ \boxed{x_{1}=\frac{-5 + \sqrt{5}}{2}} \\ \\ \\ \boxed{x_{2}=\frac{-5 - \sqrt{5}}{2}}$

Show a reciprocal numerical expression for each equation using multiplication, please!

iris [78.8K]

$\frac{2}{3}$ ÷ 4 = $\frac{2}{3} \times \frac{1}{4} = \frac{1}{6}$

$\frac{1}{8}$ ÷ 3 = $\frac{1}{8} \times \frac{1}{3} = \frac{1}{24}$

$\frac{3}{4}$ ÷ 6 = $\frac{3}{4} \times \frac{1}{6} = \frac{1}{8}$

$\frac{1}{36}$ ÷ 2 = $\frac{1}{6} \times \frac{1}{2} = \frac{1}{12}$
