How can completing the square aid in solving quadratic functions?
Elden [556K]
Completing the squares tells us exactly what square root we will need to calculate our answer.

Using the formula below you can find these answers:
A(x-h)^2 + K = 0
(x-5)^ 2 = - K/A

I will give brainliest if you answer this question !!!
yanalaym [24]

Answer:

A) 2

Step-by-step explanation:

Start off with the given information. The question states that the x-int. is 4, so you should recognize that there is a point at (4,0). Plug the point into the equation.

k(4) + 2(0) + 8 = 0

Now simplify the equation.

4k + 0 + 8 = 0

Isolate the variable, make sure it's on its own side.

4k = 8

Now get the k by itself to solve the equation. Divide both sides by 4.

k = 2

20 points!!!!! The table represents a linear function
Darya [45]
I believe the answer is 5. I multiplied 5 to -4 and that’s -20 and I’m guessing since slope-intercept form is y=Mx+b I’m thinking b=4 and the slope being 5 matches the output. -16=5(-4)+4
