Question

Solve square root of x-3 = square root of 2 subtract square root of x for...x

Solutions:
a.1/8
b.25/8
c.No solution
d.-25/8

Answer 1

This? \[\sqrt{x-3} = \sqrt{2} - \sqrt{x}\]

Answer 2

yes

Answer 3

start by squaring both sides. So, x-3 = 2 - 2sqrt(2x) + x

Then simplify: 2sqrt(2x) = 5 -> sqrt(2x) = 5/2

Answer 4

so is it b? which one is it?

Answer 5

Can you take this last equation and square both sides?

Answer 6

How? I don't know

Answer 7

Yea I dont know

Answer 8

sqrt(2x) = 5/2 -> 2x = 25 / 4, so x = 25/8

Answer 9

Finally! Thank You
