sqrt(x)sqrt(x+7)=12

x x + 7 = 12

x = 9

Solution steps

x x + 7 = 12

Square both sides:

x^{2} + 7 x = 144

x^{2} + 7 x = 144

Solve

x^{2} + 7 x = 144 : x = 9, x = - 16

x = 9, x = - 16

Verify Solutions:

x = 9

True

, x = - 16

False

The solution is

x = 9

w = 10 w - 16

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

3 x + 4 = 10

\frac{x + 26}{x + 1} = 12
