2sqrt(x)=x-3

Solution

2 x = x - 3

Solution

x = 9

Solution steps

2 x = x - 3

Square both sides:

4 x = x^{2} - 6 x + 9

4 x = x^{2} - 6 x + 9

Solve

4 x = x^{2} - 6 x + 9 : x = 9, x = 1

x = 9, x = 1

Verify Solutions:

x = 9

True

, x = 1

False

The solution is

x = 9

Popular Examples

sqrt(2x+13)=x+7

2 x + 13 = x + 7

x - x = 6

sqrt(4y+29)-sqrt(y-4)=6

4 y + 29 - y - 4 = 6

\frac{1}{3 x ^{\frac{2}{3}}} = 0

x^2+6x+sqrt(x^2+6x+8)=64

x^{2} + 6 x + x^{2} + 6 x + 8 = 64
