sqrt(x+2)=x-4

Solution

x + 2 = x - 4

Solution

x = 7

Solution steps

x + 2 = x - 4

Square both sides:

x + 2 = x^{2} - 8 x + 16

x + 2 = x^{2} - 8 x + 16

Solve

x + 2 = x^{2} - 8 x + 16 : x = 7, x = 2

x = 7, x = 2

Verify Solutions:

x = 7

True

, x = 2

False

The solution is

x = 7

Popular Examples

x^{1/2}-5x^{1/4}+4=0

x^{\frac{1}{2}} - 5 x^{\frac{1}{4}} + 4 = 0

x = 4 - x - 8

sqrt(4x+7)=sqrt(2x-3)+8

4 x + 7 = 2 x - 3 + 8

x^{1/2}-5x^{1/4}+6=0

x^{\frac{1}{2}} - 5 x^{\frac{1}{4}} + 6 = 0

(x-3)sqrt(x^2-5x+4)=2x-6

(x - 3) x^{2} - 5 x + 4 = 2 x - 6
