Question

Please help with explanations. I know that I have to square both sides.
sqrt of x =sqrt of x-5) +1

Answer 1

sqrt(x) =sqrt(x-5) +1
sqrt(x) - 1 = sqrt(x-5)
square both sides:
x - 2sqrtx + 1 = x - 5
-2sqrtx = -6
sqrtx = 3
x = 9

now check this solution if it is a solution..

Answer 2

i'll explain if you need 'em..

Answer 3

im confused with x-2sqrt +1=x-5

Answer 4

ok...
