x-2=sqrt(5x+4)

Solution

x - 2 = 5 x + 4

Solution

x = 9

Solution steps

x - 2 = 5 x + 4

Square both sides:

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

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

Solve

x^{2} - 4 x + 4 = 5 x + 4 : x = 9, x = 0

x = 9, x = 0

Verify Solutions:

x = 9

True

, x = 0

False

The solution is

x = 9

Popular Examples

sqrt(6x+1)-sqrt(x-4)=5

6 x + 1 - x - 4 = 5

sqrt(x)=-1/8 x^2+4

x = - \frac{1}{8} x^{2} + 4

sqrt(c)-4+2sqrt(c)+8=16

c - 4 + 2 c + 8 = 16

sqrt(12-n)=sqrt(2n-12)

12 - n = 2 n - 12

sqrt(8-x^2)=3x-4

8 - x^{2} = 3 x - 4
