Full solution

Q. Fully simplify.\newline9y2(9x) -9 y^{2}(-9 x) \newlineAnswer:
  1. Identify Terms: Identify the terms in the expression 9y2(9x)-9y^{2}(-9x).\newlineIn 9y2(9x)-9y^{2}(-9x), we have two terms:\newlineFirst term: 9y2-9y^{2}\newlineSecond term: 9x-9x
  2. Multiply Coefficients: Multiply the coefficients of the terms.\newlineThe coefficients are 9-9 (from the first term) and 9-9 (from the second term).\newlineMultiplying these gives us: 9×9=81-9 \times -9 = 81
  3. Multiply Variables: Multiply the variables of the terms.\newlineSince the first term has y2y^{2} and the second term has xx, when we multiply them together, we get y2xy^{2}x.
  4. Combine Results: Combine the results from Step 22 and Step 33. Multiplying the coefficient from Step 22 with the variables from Step 33 gives us: 81×y2x81 \times y^{2}x
  5. Write Final Expression: Write the final simplified expression.\newlineThe fully simplified form of the expression is 81y2x81y^{2}x.
