0.85 (1) = 1 1 - x^{2}

x = \frac{111}{20}, x = - \frac{111}{20}

Decimal Notation

x = 0.52678 \dots, x = - 0.52678 \dots

Solution steps

0.85 (1) = 1 \cdot 1 - x^{2}

Expand

1 \cdot 1 - x^{2} : 1 - x^{2}

0.85 \cdot 1 = 1 - x^{2}

Square both sides:

0.7225 = 1 - x^{2}

0.7225 = 1 - x^{2}

Solve

0.7225 = 1 - x^{2} : x = \frac{111}{20}, x = - \frac{111}{20}

x = \frac{111}{20}, x = - \frac{111}{20}

Verify Solutions:

x = \frac{111}{20}

True

, x = - \frac{111}{20}

True

The solutions are

x = \frac{111}{20}, x = - \frac{111}{20}

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

1 - 5 x = 4

3600000 = 0.2 x + 1
