Solve {c}{x^2-86x+9}{2x+2}

$$\left. \begin{array} { c } { x ^ { 2 } - 86 x + 9 } \\ { 2 x + 2 } \end{array} \right.$$

Least Common Multiple

$$2\left(x+1\right)\left(x^{2}-86x+9\right)$$

Solution Steps

Factor the expressions that are not already factored.

$$x^{2}-86x+9=\left(x-\left(-4\sqrt{115}+43\right)\right)\left(x-\left(4\sqrt{115}+43\right)\right) 2x+2=2\left(x+1\right)$$

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

$$2\left(x+1\right)\left(x^{2}-86x+9\right)$$

Expand the expression.

$$2x^{3}-170x^{2}-154x+18$$

Evaluate

$$x^{2}-86x+9,\ 2\left(x+1\right)$$
