Okay, so first you set equal to 0:

Next simplify the equation so that the leading coefficient is positive:

Looking at the quadratic equation you can't easily simplify it, so plug it into the quadratic equation and simplify:

I noticed a couple mistakes in your work, so if you want me to I can explain them in the comments section :)
A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. The number 8 is a rational number<span> because it can be written as the fraction 8/1.
I hope my answer has come to your help. God bless and have a nice day ahead!

B) 36
To figure this out you need to average the numbers. To average them you add them all up and divide by how many are there.
(60+30+20)/3
(90+20)/3
110/3
36
