I’m not sure but here’s a method that might help: write out the numbers least to greatest, the dots each represent one number, then remember that you add and divide for the mean( add up all the numbers then divide them by how many dots there are) and for median it’s the middle number, if there’s two in the middle add them and divide it by 2

Vivian is solving the equation 0=x2−5x−4 0 = x 2 − 5 x − 4 using the quadratic formula. Which value is the negative real number

Aleks [24]

<h3><u>answer</u><u>:</u></h3>

-0.7

<h3><em><u>steps</u></em><em><u>:</u></em></h3>

the quadratic formula is

$\frac{ - b + - \sqrt{ {b}^{2} - 4ac } }{2a}$

substitute the correct values in

$\frac{ - ( - 5) + - \sqrt{ {( - 5)}^{2} - 4(1)( - 4) } }{2(1)}$

where it says +- you would type this into your calculator with + AND THEN - to get two separate answers.

when you type + you get the answer of: 5.701562119...

when you type - you get the answer of:

-0.7015621187...

when you round to the nearest tenth you get -0.7
