Question

solve equation√x =x+1​

Answer 1

Answer:

x = -1±√3

2

Step-by-step explanation:

Here,

√x = x+1

squaring on both sides

x = (x+1)²

or, x = x² + 2x +1

or, x² +x +1 =0

Using formula,

x = -b ± √4a²-b²

2a

= -1 ± √4.1²-1²

2.1

= -1 ± √3

2

Either, x = -1+√3

2

Or, x = -1-√3

2

Hence, x = -1±√3
