Solve (alpha^{5}+alpha^{4}-alpha^{3}-alpha^{2}+16alpha+15)(beta^5+beta^4-beta^3-beta^2+16beta+15)

$$( \alpha ^ { 5 } + \alpha ^ { 4 } - \alpha ^ { 3 } - \alpha ^ { 2 } + 16 \alpha + 15 ) ( \beta ^ { 5 } + \beta ^ { 4 } - \beta ^ { 3 } - \beta ^ { 2 } + 16 \beta + 15 )$$

Expand

$$15\alpha ^{5}+\alpha ^{4}\beta ^{5}+15\alpha ^{4}-\alpha ^{3}\beta ^{5}-\alpha ^{3}\beta ^{4}-15\alpha ^{3}-\alpha ^{2}\beta ^{5}-\alpha ^{2}\beta ^{4}+\alpha ^{2}\beta ^{3}-15\alpha ^{2}+16\alpha \beta ^{5}+16\alpha \beta ^{4}-16\alpha \beta ^{3}-16\alpha \beta ^{2}+256\alpha \beta +240\alpha +15\beta ^{5}+\beta ^{4}\alpha ^{5}+15\beta ^{4}-\beta ^{3}\alpha ^{5}-\beta ^{3}\alpha ^{4}-15\beta ^{3}-\beta ^{2}\alpha ^{5}-\beta ^{2}\alpha ^{4}+\beta ^{2}\alpha ^{3}-15\beta ^{2}+16\beta \alpha ^{5}+16\beta \alpha ^{4}-16\beta \alpha ^{3}-16\beta \alpha ^{2}+240\beta +\left(\alpha \beta \right)^{5}+\left(\alpha \beta \right)^{4}+\left(\alpha \beta \right)^{3}+\left(\alpha \beta \right)^{2}+225$$

Evaluate

$$\left(\alpha ^{5}+\alpha ^{4}-\alpha ^{3}-\alpha ^{2}+16\alpha +15\right)\left(\beta ^{5}+\beta ^{4}-\beta ^{3}-\beta ^{2}+16\beta +15\right)$$
