Full solution

Q. Subtract −3x2+2x -3 x^{2}+2 x from −9x−1 -9 x-1 .\newlineAnswer:
  1. Distribute negative sign: Distribute the negative sign to the second polynomial. (−9x−1)−(−3x2)−(2x)(-9x - 1) - (-3x^{2}) - (2x)
  2. Simplify expression: Simplify the expression by removing the parentheses and changing the signs where necessary.\newline−9x−1+3x2−2x-9x - 1 + 3x^{2} - 2x
  3. Combine like terms: Combine like terms.\newlineSince there are no other x2x^{2} terms, the 3x23x^{2} remains as is. Combine the xx terms: −9x-9x and −2x-2x.\newline3x2+(−9x−2x)−13x^{2} + (-9x - 2x) - 1\newline3x2−11x−13x^{2} - 11x - 1
