x = 64

Solution steps

x - 3 x - 40 = 0

Remove square roots

9 x = x^{2} - 80 x + 1600

Solve

9 x = x^{2} - 80 x + 1600 : x = 64, x = 25

x = 64, x = 25

Verify Solutions:

x = 64

True

, x = 25

False

The solution is

x = 64

Popular Examples

2x^2+x+1-2sqrt(x^2+x+1)=0

2 x^{2} + x + 1 - 2 x^{2} + x + 1 = 0

x^{0.5}=sqrt(x)

x^{0.5} = x

-4=1-sqrt(x^2-11)

- 4 = 1 - x^{2} - 11

9 = 5 x - 4

2x-sqrt(5-2x)=0

2 x - 5 - 2 x = 0
