Decimal Notation

x = 8.94427 \dots, x = - 8.94427 \dots

Solution steps

Rewrite the equation with

and

x = u^{3} - 9

Solve

u = \frac{3 + 5}{2}, u = \frac{3 - 5}{2}

Substitute back

solve for

x

Solve

x = 45, x = - 45

Verify Solutions:

x = 45

True

, x = - 45

True

The solutions are

x = 45, x = - 45

x - 18 - 3 x = 0

2 = 3 - x

11 - x = x - 7

200 = 356 d

2 x - 1 + 2 x + 1 = 3
