Distribute sum groups
x(3{x}^{2}-2x+1)+5(3{x}^{2}-2x+1)x(3x​2​​−2x+1)+5(3x​2​​−2x+1)
2 Distribute
3{x}^{3}-2{x}^{2}+x+5(3{x}^{2}-2x+1)3x​3​​−2x​2​​+x+5(3x​2​​−2x+1)
3 Distribute
3{x}^{3}-2{x}^{2}+x+15{x}^{2}-10x+53x​3​​−2x​2​​+x+15x​2​​−10x+5
4 Collect like terms
3{x}^{3}+(-2{x}^{2}+15{x}^{2})+(x-10x)+53x​3​​+(−2x​2​​+15x​2​​)+(x−10x)+5
5 Simplify
3{x}^{3}+13{x}^{2}-9x+53x​3​​+13x​2​​−9x+5
