x+2=sqrt(2x+7)

Solution

x + 2 = 2 x + 7

Solution

x = 1

Solution steps

x + 2 = 2 x + 7

Square both sides:

x^{2} + 4 x + 4 = 2 x + 7

x^{2} + 4 x + 4 = 2 x + 7

Solve

x^{2} + 4 x + 4 = 2 x + 7 : x = 1, x = - 3

x = 1, x = - 3

Verify Solutions:

x = 1

True

, x = - 3

False

The solution is

x = 1

Popular Examples

x + 1 + 1 = 0

1= 1/(3x^{2/3)}

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

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

x - 1 = x - 3

sqrt(2-x^2)+sqrt(4-x^2)=2x

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

(37-2x^2)/(sqrt(37-x^2))=0

\frac{37 - 2 x ^{2}}{37 - x ^{2}} = 0
