Identify Terms: Identify the terms in the expression −9y2(−9x).In −9y2(−9x), we have two terms:First term: −9y2Second term: −9x
Multiply Coefficients: Multiply the coefficients of the terms.The coefficients are −9 (from the first term) and −9 (from the second term).Multiplying these gives us: −9×−9=81
Multiply Variables: Multiply the variables of the terms.Since the first term has y2 and the second term has x, when we multiply them together, we get y2x.
Combine Results: Combine the results from Step 2 and Step 3. Multiplying the coefficient from Step 2 with the variables from Step 3 gives us: 81×y2x
Write Final Expression: Write the final simplified expression.The fully simplified form of the expression is 81y2x.
