2sqrt(x+5)=x+2

Solution

2 x + 5 = x + 2

Solution

x = 4

Solution steps

2 x + 5 = x + 2

Square both sides:

4 x + 20 = x^{2} + 4 x + 4

4 x + 20 = x^{2} + 4 x + 4

Solve

4 x + 20 = x^{2} + 4 x + 4 : x = 4, x = - 4

x = 4, x = - 4

Verify Solutions:

x = 4

True

, x = - 4

False

The solution is

x = 4

Popular Examples

sqrt(x^2-2)-x=3

x^{2} - 2 - x = 3

x - 6 x = - 9

sqrt(2x^2-6x+2)=sqrt(x^2-3x)

2 x^{2} - 6 x + 2 = x^{2} - 3 x

sqrt(2x+11)=sqrt(3x+7)

2 x + 11 = 3 x + 7

(x/(5+5))^{3/2}=125

(\frac{x}{5 + 5})^{\frac{3}{2}} = 125
