Algebra Examples

$x = 1 + - \sqrt{5}$

Step 1

Replace all occurrences of $+$ $-$ with a single $-$ . A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because $1 \cdot - 1 = - 1$

$x = 1 - \sqrt{5}$

Step 2

The result can be shown in multiple forms.

Exact Form:

$x = 1 - \sqrt{5}$

Decimal Form:

$x = - 1.23606797 \dots$
