Solve {l}{2y^2(y+2)+13y(y+2)+15(y+2)}{c^4-8c^2+12}

$$\left. \begin{array} { l } { 2 y ^ { 2 } ( y + 2 ) + 13 y ( y + 2 ) + 15 ( y + 2 ) } \\ { c ^ { 4 } - 8 c ^ { 2 } + 12 } \end{array} \right.$$

Least Common Multiple

$$\left(y+2\right)\left(y+5\right)\left(2y+3\right)\left(c^{2}-6\right)\left(c^{2}-2\right)$$

Solution Steps

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

$$\left(y+2\right)\left(y+5\right)\left(2y+3\right)\left(c^{2}-6\right)\left(c^{2}-2\right)$$

Expand the expression.

$$2y^{3}c^{4}-16c^{2}y^{3}+24y^{3}+17y^{2}c^{4}-136c^{2}y^{2}+204y^{2}+41yc^{4}-328yc^{2}+492y+30c^{4}-240c^{2}+360$$

Evaluate

$$\left(y+2\right)\left(y+5\right)\left(2y+3\right),\ \left(c^{2}-6\right)\left(c^{2}-2\right)$$
