Question

sqrt(x) = x - 2. solve for x.

Answer 1

first square the whole thing
x=(x-2)^2
x=x^2-4x+4
make equation equal 0
x^2-5x+4=0
use the quadratic formula

Answer 2

square both sides, solve the resulting quadratic equation, check your answer

Answer 3

this is a hell of a lot easier than solving partial fractions!!

Answer 4

haha... this is part of a larger problem

Answer 5

whew

Answer 6

i don't think you even need the quadratic formula

Answer 7

(x-4)(x-1)=0

Answer 8

\(x^2-5x+4=0\)
\((x-4)(x-1)=0\) etc

Answer 9

of course \(1\) is not a solution, only \(4\) is

Answer 10

why

Answer 11

whhhyyy

Answer 12

@satellite73 why is 1 not a solution
