How do you find zeros when given a quadratic relation in vertex form

In order to find the zeros in a quadratic in vertex form, you need to follow a number of steps. They have been outlined for you along with a sample problem.

y = (x - 2)^2 - 16

After getting the original form, you can place a 0 in for y. In is where the graph will cross the x-axis, so it is where you will find both of your zeros.

0 = (x - 2)^2 - 16

Now take the constant and add it to both sides. In this equation, -16 is your constant. So, we'll add 16 to both sides to begin to solve.

16= (x - 2)^2

Now we can take the square root of both sides. After we do so, we take both the positive and negative version of what we get. This is because both 4 and -4 squared is equal to 16.

+/-4 = x - 2

Now we add 2 to both sides to get us what is left of x.

2 +/- 4 = x

Now that we have a final form such as this, we can separate and get two answers for our two zeros.

2 + 4 = 6

2 - 4 = -2

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
