Full solution

Q. (−5m2−8)−(−3m2+m+2)=(-5m^2-8) -(-3m^2+m+2)=
  1. Distribute negative sign: Distribute the negative sign to the second expression.\newlineWe need to distribute the negative sign across each term in the second expression (−3m2+m+2)(-3m^2 + m + 2).\newline(−5m2−8)−(−3m2+m+2)=(−5m2−8)+(3m2−m−2)(-5m^2 - 8) - (-3m^2 + m + 2) = (-5m^2 - 8) + (3m^2 - m - 2)
  2. Combine like terms: Combine like terms.\newlineNow we combine the terms with the same variable powers and the constant terms.\newline(−5m2+3m2)+(−m)+(−8−2)(-5m^2 + 3m^2) + (-m) + (-8 - 2)\newline=−2m2−m−10= -2m^2 - m - 10
