Solve {l}{-2-2x^2}{1-1}{x^2+x-1-1-x+x^2}

$$\left. \begin{array} { l } { - 2 - 2 x ^ { 2 } } \\ { 1 - 1 } \\ { x ^ { 2 } + x - 1 - 1 - x + x ^ { 2 } } \end{array} \right.$$

Least Common Multiple

$$0$$

Solution Steps

Factor the expressions that are not already factored.

$$-2-2x^{2}=2\left(-x^{2}-1\right) 2x^{2}-2=2\left(x-1\right)\left(x+1\right)$$

Identify all the factors and their highest power in all expressions. Multiply the highest powers of these factors to get the least common multiple.

$$0$$

Evaluate

$$-2x^{2}-2,\ 0,\ 2x^{2}-2$$
