x\times sqrt(x+7)=6

x \cdot x + 7 = 6

x = 2

Solution steps

x x + 7 = 6

Square both sides:

x^{3} + 7 x^{2} = 36

x^{3} + 7 x^{2} = 36

Solve

x^{3} + 7 x^{2} = 36 : x = 2, x = - 3, x = - 6

x = 2, x = - 3, x = - 6

Verify Solutions:

x = 2

True

, x = - 3

False

, x = - 6

False

The solution is

x = 2

2 x - 1 = 4

x + 3 + 2 = - 2 x + 6

1 - 4 x = 10

y, x y + 4 = y

3 6 x - 5 = 3 3 x + 8
