What are the exact solutions of x2 + 5x + 1 = 0? (5 points)
Rus_ich [418]

Answer:

x=\frac{-5\pm\sqrt{21}  }{2}

Step-by-step explanation:

We use the quadratic formula here which says for a quadratic equation ax^2+bx+c=0.

x= \frac{-b\pm\sqrt{b^2-4ac} }{2a}

Now in our case

a=1\\b=5\\c=1

so we have:

x=\frac{-5\pm\sqrt{5^2-4(1)(1)}  }{2(1)} =\frac{-5\pm\sqrt{21}  }{2}

\boxed{x=\frac{-5\pm\sqrt{21}  }{2} }

Which are our solutions.
