Determine which equation has the same solutions as the given equation
2x^2 - 12x - 50 = 0
a. (x-3)^2 = 16
b. (x - 6)^2 = 19
c. (x - 6)^2 = 31
d. (x - 3)^2 = 34

Step-by-step explanation:

here is the answer ....feel free to ask if u don't get it

D.

Step-by-step explanation:

Its looks like they have complete the square for the given equation.

So let's do that.

I see all of my terms are even so I can easily divide each of them by 2.

I'm going to divide both sides by 2:

The first step in completing the square is to make sure the coefficient of is 1 so we can use this easy formula:

.

So I see in place of k I have -6.

I'm going to add on both sides.

See these first three terms here can be written using the mentioned formula:

Let's simplify a bit:

Add 25 on both sides:

4
