What is the solution set of x2 + 5x + 1 = 0?

DerKrebs [107]

Answer:

$\huge\boxed{\left\{-\dfrac{5+\sqrt{21}}{2};\ \dfrac{-5+\sqrt{21}}{2}\right\}}$

Step-by-step explanation:

$x^2+5x+1=0\\\\\text{Use the quadratic formula:}\\\\\text{For}\ ax^2+bx+c=0\\\\\Delta=b^2-4ac\\\\\text{if}\ \Delta < 0,\ \text{then the equation has no real solution}\\\text{if}\ \Delta=0,\ \text{then the equation has one real solution}\ x=\dfrac{-b}{2a}\\\text{if}\ \Delta>0,\ \text{then the equation has two real solution}\ x=\dfrac{-b\pm\sqrt{\Delta}}{2a}$

$\text{We have}\\\\a=1,\ b=5,\ c=1\\\\\Delta=5^2-4(1)(1)=25-4=21>0\\\\x=\dfrac{-5\pm\sqrt{21}}{2(1)}=\dfrac{-5\pm\sqrt{21}}{2}$

Cindy and Jose were in charge of selling tickets to the class play. Cindy sold 40 tickets and Jose sold 28 tickets. What is the

FrozenT [24]

Answer:

10:17

Step-by-step explanation:

If I am making a ratio of the tickets Cindy sold to the number of tickets sold in all it would be 40:68 but I would have to simplify and 40 divided by 2 = 20 and 68 divided by 2 = 34 then I would divide them both by two again to get our answer of 10:17! Hope this helps! Have a great day!
