x=sqrt(2x+15)

Solution

x = 2 x + 15

Solution

x = 5

Solution steps

x = 2 x + 15

Square both sides:

x^{2} = 2 x + 15

x^{2} = 2 x + 15

Solve

x^{2} = 2 x + 15 : x = 5, x = - 3

x = 5, x = - 3

Verify Solutions:

x = 5

True

, x = - 3

False

The solution is

x = 5

Popular Examples

3 x = 6

(((9-x)(3-sqrt(x))))/((3+sqrt(x)))=1

\frac{( ( 9 - x ) ( 3 - x ) )}{( 3 + x )} = 1

x - 8 = 5

sqrt(2y+\sqrt{2y+4)}=4

2 y + 2 y + 4 = 4

x^2-2sqrt(3x)-6=0

x^{2} - 2 3 x - 6 = 0
