6=sqrt(8-x)*sqrt(-8-x)

6 = 8 - x \cdot - 8 - x

x = - 10

Solution steps

6 = 8 - x - 8 - x

Square both sides:

36 = - 64 + x^{2}

36 = - 64 + x^{2}

Solve

36 = - 64 + x^{2} : x = 10, x = - 10

x = 10, x = - 10

Verify Solutions:

x = 10

False

, x = - 10

True

The solution is

x = - 10

x^{2} - 1 = - 4 x

x = \frac{1}{2}

0 = 18 5 x + 10

x + 2 x + 1 = 7

x - 4 = 40 - 6 x
