sqrt(7-2x)=x-2

Solution

7 - 2 x = x - 2

Solution

x = 3

Solution steps

7 - 2 x = x - 2

Square both sides:

7 - 2 x = x^{2} - 4 x + 4

7 - 2 x = x^{2} - 4 x + 4

Solve

7 - 2 x = x^{2} - 4 x + 4 : x = 3, x = - 1

x = 3, x = - 1

Verify Solutions:

x = 3

True

, x = - 1

False

The solution is

x = 3
