sqrt(-2x+21)=x-3

Solution

- 2 x + 21 = x - 3

Solution

x = 6

Solution steps

- 2 x + 21 = x - 3

Square both sides:

- 2 x + 21 = x^{2} - 6 x + 9

- 2 x + 21 = x^{2} - 6 x + 9

- 2 x + 21 = x^{2} - 6 x + 9 : x = 6, x = - 2

x = 6, x = - 2

Verify Solutions:

x = 6

True

, x = - 2

False

The solution is

x = 6
