This is the quadratic formula.
5.8/1.2 = 58/12 = 4.83333333
rounded to the nearest hundredth
4.83
Step-by-step explanation:
AB = 3
by similaritiy criterion
CE/ CB= ED/AB
4/6= 2/AB
AB = 3

the y intercept is the constant term on the x side
-6 * -2 which is 12
we can foil this out to see that
(x-6) (x-2)
x^2 -6x -2x+12
x^2 -8x+12
so the y intercept is (0,12)
