\( \normalsize p\cdot\left(3+p\right)-5\cdot\left(p^2+3\right)-2p\cdot\left(p+1\right) \)
\( \large = \left( {{p^{2}} - 5{p^{2}} + 2{p^{2}}} \right) + \left( {3p+ 2p} \right) - 15 =- 2{p^{2}} + 5p- 15 = 5p- 2{p^{2}} - 15 \)
\( \large = \left( {{p^{2}} - 5{p^{2}} - 2{p^{2}}} \right) + \left( {3p- 2p} \right) - 10 =- 6{p^{2}} + p- 10 = p- 6{p^{2}} - 10 \)
\( \large = \left( {{p^{2}} - 5{p^{2}} - 2{p^{2}}} \right) + \left( {3p- 2p} \right) - 15 =- 6{p^{2}} + p- 15 = p- 6{p^{2}} - 15 \)
\( \large = \left( {{p^{2}} + 5{p^{2}} - 2{p^{2}}} \right) + \left( {3p- 2p} \right) - 15 = 4{p^{2}} + p- 15 = p+ 4{p^{2}} - 15 \)
