1.8 = x (x + 2)

x = \frac{- 5 + 106}{5}, x = - \frac{5 + 106}{5}

Decimal Notation

x = 1.05912 \dots, x = - 3.05912 \dots

Solution steps

1.8 = x (x + 2)

Square both sides:

3.24 = x^{2} + 2 x

3.24 = x^{2} + 2 x

Solve

3.24 = x^{2} + 2 x : x = \frac{- 5 + 106}{5}, x = - \frac{5 + 106}{5}

x = \frac{- 5 + 106}{5}, x = - \frac{5 + 106}{5}

Verify Solutions:

x = \frac{- 5 + 106}{5}

True

, x = - \frac{5 + 106}{5}

True

The solutions are

x = \frac{- 5 + 106}{5}, x = - \frac{5 + 106}{5}

3 x + 3 - x + 5 = 2

x^{5} = 32

y, x = - 1 + y

x, 9 = 6 x - 3

30 - 4 x + 4 x^{2} - 60 x + 330 = 36
