x-9=sqrt(4x+9)

Solution

x - 9 = 4 x + 9

Solution

x = 18

Solution steps

x - 9 = 4 x + 9

Square both sides:

x^{2} - 18 x + 81 = 4 x + 9

x^{2} - 18 x + 81 = 4 x + 9

Solve

x^{2} - 18 x + 81 = 4 x + 9 : x = 18, x = 4

x = 18, x = 4

Verify Solutions:

x = 18

True

, x = 4

False

The solution is

x = 18

Popular Examples

sqrt(x+201)-sqrt(x+25)=8

x + 201 - x + 25 = 8

(4 x)^{\frac{1}{3}} - x = 0

x*sqrt(-2x^2+6x+1)=-4x^2+6x+1

x \cdot - 2 x^{2} + 6 x + 1 = - 4 x^{2} + 6 x + 1

a^{\frac{1}{2}} = 5

x = 9
