Video Solution

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify like terms.
  • Step 2: Simplify the expression by combining like terms.

Let's simplify the given expression:
The expression is given as x×y3x×x+2y×y6x2 x \times y - 3x \times x + 2y \times y - 6x^2 .

First, simplify each term:
- x×y x \times y remains xy xy .
- 3x×x 3x \times x simplifies to 3x2 3x^2 .
- So, the expression becomes xy3x2+2y26x2 xy - 3x^2 + 2y^2 - 6x^2 .

Next, combine like terms:
- Combine the x2 x^2 terms: 3x26x2=9x2 -3x^2 - 6x^2 = -9x^2 .
- The xy xy term and 2y2 2y^2 term are unique and remain as they are.

This results in the simplified expression: xy9x2+2y2 xy - 9x^2 + 2y^2 .

Upon comparing this simplification with the answer choices, the correct option is:

xy9x2+2y2 xy - 9x^2 + 2y^2

Therefore, the solution to the problem is xy9x2+2y2 xy - 9x^2 + 2y^2 .

Answer

xy9x2+2y2 xy-9x^2+2y^2
