x² = 256
x = ±√256
x = ±16

 the solutions are x = -16 and x = 16

X = 16
x = - 16

You could do it this way
x^2 - 256 = 0
(x - 16)(x + 16) = 0
x - 16 = 0
x = 16

x + 16 = 0
x = - 16

What is the solution to the equation 2(x - 3) = 2x + 5

Genrish500 [490]

Hello there!

2(x - 3) = 2x + 5

Let's start by using the distributive property for the left side.

(2)(x) + (2)(-3) = 2x + 5

2x - 6 = 2x + 5

Then we need to add 6 to both sides

2x - 6 + 6 = 2x + 5 + 6

2x = 2x + 11

We need to transfer 2x on the left side, we gonna do that by subtracting 2x from both sides

2x - 2x = 2x + 11 - 2x

0 = 11

Thus,

There are no solutions.

I hope this helps!

Good luck with your career!
