sqrt(-4x+72)=x-3

Solution

- 4 x + 72 = x - 3

Solution

x = 9

Solution steps

- 4 x + 72 = x - 3

Square both sides:

- 4 x + 72 = x^{2} - 6 x + 9

- 4 x + 72 = x^{2} - 6 x + 9

Solve

- 4 x + 72 = x^{2} - 6 x + 9 : x = 9, x = - 7

x = 9, x = - 7

Verify Solutions:

x = 9

True

, x = - 7

False

The solution is

x = 9
