sqrt(x+4)=3x-12

Solution

x + 4 = 3 x - 12

Solution

x = 5

Solution steps

x + 4 = 3 x - 12

Square both sides:

x + 4 = 9 x^{2} - 72 x + 144

x + 4 = 9 x^{2} - 72 x + 144

Solve

x + 4 = 9 x^{2} - 72 x + 144 : x = 5, x = \frac{28}{9}

x = 5, x = \frac{28}{9}

Verify Solutions:

x = 5

True

, x = \frac{28}{9}

False

The solution is

x = 5
