Determine the missing step for solving the quadratic equation by completing the square.
0 = –6x2 + 24x – 5
5 = –6x2 + 24x
5 = –6(x2 – 4x)
inside the parentheses and .
–19 = –6(x – 2)2
startfraction 19 over 6 endfraction = (x – 2)2
plus or minus startroot startfraction 19 over 6 endfraction endroot = x – 2
the two solutions are plus or minus startroot startfraction 19 over 6 endfraction endroot.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2

actually what is a question i don't understand
