Question

Solve: x=4+(4x-4)1/2 x = 2

x = 10
x = 2 or x = 10
no real solution

Answer 1

No real solution- Not any of the options anyway

Explanation:

So I replaced the x's with the two possible equations and then tried to solve...

2=4+(4x2-4)1/2

2=4+(8-4)1/2

2=4+(4)1/2

2=8(1/2)

2=4 Which is not true

10=4+(4x10-4)1/2

10=4+(40-4)1/2

10=4+36(1/2)

10=40(1/2)

10=20 Which is also not true

Therefore, there is no real solution
