Answer:

Step-by-step explanation:

The given equation is expressed as

√2x + 9 - √x + 4 = 0

Adding √x + 4 to the left hand side and the right hand side of equation, it becomes

√2x + 9 = √x + 4

Squaring the left hand side and the right hand side of equation, it becomes

2x + 9 = x + 4

Subtracting x from the left hand side and the right hand side of equation, it becomes

2x - x + 9 = 4

x + 9 = 4

Subtracting 9 from the left hand side and the right hand side of equation, it becomes

x = 4 - 9

x = - 5
