sqrt(12+x)=x

Solution

12 + x = x

Solution

x = 4

Solution steps

12 + x = x

Square both sides:

12 + x = x^{2}

12 + x = x^{2}

Solve

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

x = 4, x = - 3

Verify Solutions:

x = 4

True

, x = - 3

False

The solution is

x = 4

sqrt(2x+3)-2sqrt(x-2)=1

2 x + 3 - 2 x - 2 = 1

x^2+6x=13sqrt(x^2+6x)-36

x^{2} + 6 x = 13 x^{2} + 6 x - 36

5 - 4 x - x = 0

(2x+3)/(x-1)=sqrt(x)

\frac{2 x + 3}{x - 1} = x
