Question

2. SUBTRACT: x2 + 3xy-y2 from x2 + 5xy​

Answer 1

Answer:

   y² + 2 x y

Step-by-step explanation:

Given polynomials

                 x² + 3x y -y²   and x² + 5xy

The subtract  x² + 3x y -y²   from x² + 5xy

                  x² + 5xy - ( x² + 3x y -y²)

          ⇒     x² + 5xy -x² - 3xy +y²

       ⇒        2 x y + y²
