Distribute negative sign: Distribute the negative sign to the second polynomial. (−9x−1)−(−3x2)−(2x)
Simplify expression: Simplify the expression by removing the parentheses and changing the signs where necessary.−9x−1+3x2−2x
Combine like terms: Combine like terms.Since there are no other x2 terms, the 3x2 remains as is. Combine the x terms: −9x and −2x.3x2+(−9x−2x)−13x2−11x−1
