Square root of the quantity x minus 2 end quantity plus 8 equals x
Butoxors [25]

ANSWER

x=11

EXPLANATION

We want to solve the equation:

\sqrt{x - 2}  + 8 = x

Add -8 to both sides:

\sqrt{x - 2} = x - 8

Square both sides of the equation to get:

(\sqrt{x - 2} )^{2} =( x - 8)^{2}

x - 2 =  {x}^{2}  - 16x + 64

Rewrite in the form ax² +bx+c=0

{x}^{2}  - 16x - x + 64 + 2 = 0

{x}^{2}  - 17x + 66 = 0

Factor to get,

(x - 11)(x - 6) = 0

This implies that,

x = 11 \: or \: x = 6

Checking for extraneous solutions.

When x=6, the original equation becomes,

\sqrt{6- 2}  + 8 = 6

\sqrt{4 }  + 8 = 6

2+8= 6 is not true.

x=6 is an extraneous solution.

When x=11, the original equation becomes,

\sqrt{11- 2}  + 8 = 11

\sqrt{9}  + 8 = 11

3 + 8 = 11

This is true, hence x=11 is the only solution.
