Answer 1

$intlimits^6_0 { frac{(x^{2}-1)(x^{2}+1)}{(x+1)} } , dx = intlimits^6_0 { frac{(x-1)(x+1)(x^{2}+1)}{(x+1)} } , dx=$$=intlimits^6_0 {(x-1)(x^{2}+1) } , dx=intlimits^6_0 {(x^{3}-x^{2}+x-1) } , dx= frac{x^{4}}{4}-frac{x^{3}}{3}+frac{x^{2}}{2}-x|^{6}_{0}=frac{6^{4}}{4}-frac{6^{3}}{3}+frac{6^{2}}{2}-6=frac{3*6^{4}-4*6^{3}+6*6^{2}-72}{12}=frac{3*6^{4}-3*6^{3}-72}{12}=frac{3*6^{3}*5-72}{12}=frac{3168}{12}=264$
