How can i solve this expression with polynomials?

(m^2+m+1)*(m^2-m-1)*(m-1)-2m(m^2+1)

  m⁴ - 2m³ - m² - 4m - 1

Step-by-step explanation:

FYI: You cannot "solve" the expression because there is no equality (=) symbol.

Simplify: (m² + m + 1)(m² - m - 1)  -  2m(m² + 1)

Multiply the expressions using distributive method:

m²(m² - m - 1) + m(m² - m - 1) + 1(m² - m - 1)    -2m(m² + 1)

m⁴ - m³ - m²   + m³ - m² - m   + (m² - m - 1)    -2m³ - 2m

Add like terms:

m⁴ - 2m³ - m² - 4m - 1
