sqrt(6x+40)=x+8

6 x + 40 = x + 8

x = - 4, x = - 6

Solution steps

6 x + 40 = x + 8

Square both sides:

6 x + 40 = x^{2} + 16 x + 64

6 x + 40 = x^{2} + 16 x + 64

Solve

6 x + 40 = x^{2} + 16 x + 64 : x = - 4, x = - 6

x = - 4, x = - 6

Verify Solutions:

x = - 4

True

, x = - 6

True

The solutions are

x = - 4, x = - 6

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

x^{\frac{1}{2}} - 9 x^{\frac{1}{4}} + 20 = 0

21 - 5 x = x - 3

x^{\frac{2}{3}} + 2 x^{\frac{1}{3}} - 3 = 0

x = 1 + x + 11
