2x=sqrt(30+2x)

Solution

2 x = 30 + 2 x

Solution

x = 3

Solution steps

2 x = 30 + 2 x

Square both sides:

4 x^{2} = 30 + 2 x

4 x^{2} = 30 + 2 x

Solve

4 x^{2} = 30 + 2 x : x = 3, x = - \frac{5}{2}

x = 3, x = - \frac{5}{2}

Verify Solutions:

x = 3

True

, x = - \frac{5}{2}

False

The solution is

x = 3

Popular Examples

sqrt(x^2-9)=x-3

x^{2} - 9 = x - 3

sqrt(x+10)-sqrt(2x-5)=0

x + 10 - 2 x - 5 = 0

4 x - 7 = 3

7-sqrt(y)=sqrt(y-35)

7 - y = y - 35

sqrt(m)+1=sqrt(m+10)

m + 1 = m + 10
