sqrt(x-3)=x-9

Solution

x - 3 = x - 9

Solution

x = 12

Solution steps

x - 3 = x - 9

Square both sides:

x - 3 = x^{2} - 18 x + 81

x - 3 = x^{2} - 18 x + 81

Solve

x - 3 = x^{2} - 18 x + 81 : x = 12, x = 7

x = 12, x = 7

Verify Solutions:

x = 12

True

, x = 7

False

The solution is

x = 12

Popular Examples

3 = 2 x - 1

sqrt(x^2+2x-25)=sqrt(x+5)

x^{2} + 2 x - 25 = x + 5

2 x - 1 - 5 = 0

64=(x^2)/(sqrt(x))

64 = \frac{x ^{2}}{x}

(x - 1)^{\frac{3}{2}} = 64
