Question

Simplify m(m^3-m^2+1)-2(m^4-m^3-1)+m^2(m^2-m+2)​

Answer 1

$= > m ({m}^{3} - {m}^{2} + 1) - 2( {m}^{4} - {m}^{3} - 1) + {m}^{2} ( {m}^{2} - m + 2)$

$= > {m}^{4} - {m}^{3} + m - 2 {m}^{4} + 2 {m}^{3} + 2 - {m}^{4} - {m}^{3} + 2 {m}^{2}$

$= > - 2{m}^ {4} + 2 {m}^{2} + m + 2$

Hope this answer helps you ^_^ !
