Question

Solve for x:
√2x+5-1=x

Answer 1

\(\large \sqrt{2x+5} - 1 = x\)

Answer 2

like that ?

Answer 3

yes

Answer 4

add 1 both sides, square both sides

Answer 5

\(\large \sqrt{2x+5} - 1 = x \)
+1 +1

Answer 6

√2x+5-1=x
√2x+5=x+1
squaring both side
2x+5=(x+1)^2
2x+5=x^2+2x+1
x^2+2x-2x-5+1=0
x^2-4=0
x^2=4
x=+-sqrt(4)
x=+-2
x=2 or x=-2
