Q. y2(6xy) -y^{2}(6 x-y) \newlineWhich of the following is equivalent to the given expression?\newlineChoose 11 answer:\newline(A) 6x3+x2y -6 x^{3}+x^{2} y \newline(B) 6x2y+y3 -6 x^{2} y+y^{3} \newline(C) 6xy2+y3 -6 x y^{2}+y^{3} \newline(D) 6xy2y3 6 x y^{2}-y^{3}
  1. Distribute y2-y^{2}: We need to distribute the term y2-y^{2} across the terms inside the parentheses (6xy)(6x-y). This is done by multiplying y2-y^{2} with each term inside the parentheses separately.\newlineCalculation: y2×6x+y2×y-y^{2} \times 6x + y^{2} \times y
  2. Multiply with 6x6x: Multiplying y2-y^{2} by 6x6x gives us 6xy2-6xy^{2}. This is a straightforward multiplication of a constant with a variable term.\newlineCalculation: y2×6x=6xy2-y^{2} \times 6x = -6xy^{2}
  3. Multiply with y-y: Multiplying y2y^{2} by y-y gives us y3-y^{3}. This is a multiplication of a variable term with itself, which results in raising the power by 11.\newlineCalculation: y2×y=y3y^{2} \times -y = -y^{3}
  4. Combine results: Combining the results from the previous steps, we get the final expression: 6xy2y3-6xy^{2} - y^{3}.\newlineCalculation: 6xy2+(y3)=6xy2y3-6xy^{2} + (-y^{3}) = -6xy^{2} - y^{3}
