x-1=sqrt(2x+6)

Solution

x - 1 = 2 x + 6

Solution

x = 5

Solution steps

x - 1 = 2 x + 6

Square both sides:

x^{2} - 2 x + 1 = 2 x + 6

x^{2} - 2 x + 1 = 2 x + 6

Solve

x^{2} - 2 x + 1 = 2 x + 6 : x = 5, x = - 1

x = 5, x = - 1

Verify Solutions:

x = 5

True

, x = - 1

False

The solution is

x = 5

Popular Examples

sqrt(x+1)-1-x=0

x + 1 - 1 - x = 0

sqrt(x^2+81)=x+10

x^{2} + 81 = x + 10

3 x + 7 = x + 1

sqrt(4x^2-20x+25)=5-2x

4 x^{2} - 20 x + 25 = 5 - 2 x

x+1=3+sqrt(2x-1)

x + 1 = 3 + 2 x - 1
