Please help my assignment is due at 12:00!!
Brums [2.3K]

Answer: -13, -12.9

Step-by-step explanation:

pull out that HANDY DANDY calculator dog because we are about to go on a MATH ADVENTURE oh yea.

ok first make sure it is a reasonably good calculator but you can even use a calculator on your chromebook, maybe an online one? we need one that gives us PARENTHESES.

ok now you are going to want to input into this calculator, (335 / 2) in other words 335 divided by 2. what do we get? we get

167.5

ok cool WE ARE MAKING PROGRESS HERE!!!

now i want you to look for the square root button, it looks like a radical like this

\sqrt[2]{} or MAYBE IT DOESNT EVEN HAVE THE 2 and it is just: \sqrt[]{}

and press it, it should give you the square root but we want to find \sqrt{167.5}

and we get.....

12.942...

MY GOD THAT IS A SUPER LONG NUMBER! but its ok we only need 3 digits after the decimal. now notice that there is a negative sign behind that radical. thats radical, dude, ok now we have -12.942...

if we round to the nearest INTEGER then we need to round to the nearest WHOLE NUMBER which is

-13

and the nearest TENTH is one number after the decimal place so it would be...

-12.9

SURFS UP DUDE

P.S. i mention the parentheses because you can even do \sqrt{(335/2)} (press square root button then opening parentheses then 335 / 2 then close parentheses and hit equal sign or ENTER) but dont forget that EPIC NEGATIVE SIGN!!!!!!!

Use the Quadratic Formula to solve x2 + 20x + 98 = 0
Lubov Fominskaja [6]
ax^2+bx+c=0\\\\\Delta=b^2-4ac\\\\if\ \Delta \ \textless \  0\ then\ no\ solution\\\\if\ \Delta =0\ then\ one\ solution\ x_0=\dfrac{-b}{2a}\\\\if\ \Delta \ \textgreater \  0\ then\ two\ solutions\ x_1=\dfrac{-b-\sqrt\Delta}{2a}\ and\ x_2=\dfrac{-b+\sqrt\Delta}{2a}\\-----------------------------

x^2+20x+98=0\\a=1;\ b=20;\ c=98\\\\\Delta=20^2-4\cdot1\cdot98=400-392=8 \ \textgreater \  0\\\sqrt\Delta=\sqrt8=\sqrt{4\cdot2}=\sqrt4\cdot\sqrt2=2\sqrt2\\\\x_1=\dfrac{-20-2\sqrt2}{2\cdot1}=\dfrac{-20-2\sqrt2}{2}=-10-\sqrt2\\\\x_2=\dfrac{-20+2\sqrt2}{2\cdot1}=\dfrac{-20+2\sqrt2}{2}=-10+\sqrt2
