Question

Solve for x: (x-4)2 =2

the work:
first simplify (x-4)2 which = 2x-8 (2 times x + 2 times -4)

2x-8=2

then you have to bring the -8 over by the other side by adding 8 to both sides. Whatever you do on one side you have to do on the other to balance the equation.

2x-8+8 = 2+8

2x = 10

Divide both sides by 2 to get x by itself.

2x/2 = 10/2

x= 5


BUT..... which one is it?

x = 4 ± 2 sq root 2
x = 4 ± sq root 13
x = 4 ± sq root 2
x = 4 ± 2 sq root 13

Answer 1

why you are making the simple problem too difficult....

Answer 2

:/ ouch

Answer 3

I was solving it is all

Answer 4

( x - 4 )2 = 2
( x - 4 ) = 1 dividing both sides by 2
x = 5 adding 5 to both sides

Answer 5

It still doesn't help me

Answer 6

no offense

Answer 7

I think you are write the question something is missing. Do you mean (x-4)^2=2?
