sqrt(3-x)=x-1

Solution

3 - x = x - 1

Solution

x = 2

Solution steps

3 - x = x - 1

Square both sides:

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

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

Solve

3 - x = x^{2} - 2 x + 1 : x = 2, x = - 1

x = 2, x = - 1

Verify Solutions:

x = 2

True

, x = - 1

False

The solution is

x = 2

Popular Examples

(x^2+20x)^{4/3}=625

(x^{2} + 20 x)^{\frac{4}{3}} = 625

sqrt(2x+49)=sqrt(x)+5

2 x + 49 = x + 5

sqrt(x-\sqrt{1-x)}+sqrt(x)=1

x - 1 - x + x = 1

sqrt(x+7)=-x^2+5

x + 7 = - x^{2} + 5

sqrt(x+1)+sqrt(x+4)=3

x + 1 + x + 4 = 3
