Question

multiply :(3xy square + 4x square)×(3x square-xy square)​

Answer 1

Answer:

(3xy^2 + 4x^2) x (3x^2 - xy^2) = 12x^4 + 5x^3y^2 - 3x^2y^4 (or)                                 x^2 [12x^2 + 5xy^2 - 3y^2]

Step-by-step explanation:

→ (3xy^2 + 4x^2) x (3x^2 - xy^2)

→ 9x^3y^2 + 12x^4 - 3x^2y^4 - 4x^3y^2

→5x^3y^2 + 12x^4 - 3x^2y^4

→12x^4 + 5x^3y^2 - 3x^2y^4 (or) x^2 [12x^2 + 5xy^2 - 3y^2]
