Q. 2x(3x+y) 2 x(3 x+y) \newlineWhich of the following is equivalent to the given expression?\newlineChoose 11 answer:\newline(A) 5x2+2xy 5 x^{2}+2 x y \newline(B) 5x2+y 5 x^{2}+y \newline(C) 6x2+2y 6 x^{2}+2 y \newline(D) 6x2+2xy 6 x^{2}+2 x y
  1. Distribute 2x2x: We need to distribute the term 2x2x across the terms inside the parentheses (3x+y)(3x+y). This means we will multiply 2x2x by each term inside the parentheses separately.\newlineCalculation: 2x×3x+2x×y2x \times 3x + 2x \times y
  2. Multiply 2x2x by 3x3x: First, multiply 2x2x by 3x3x.\newlineCalculation: 2x×3x=6x22x \times 3x = 6x^2
  3. Multiply 2x2x by yy: Next, multiply 2x2x by yy.\newlineCalculation: 2x×y=2xy2x \times y = 2xy
  4. Combine results: Combine the results from the two multiplications to get the final expression.\newlineCalculation: 6x2+2xy6x^2 + 2xy
