Question

please help me it's very very urgent ☺️​

Answer 1

Step-by-step explanation:

(xii) 3x²(y² + 4) - 2y²(y² + 4)

= (3x² - 2y²) (y² + 4)

(xiii) 5y³(x²-5) - 2y²(x²-5)+ 3y(x²-5)

= (5y³ - 2y² + 3y) (x²-5)

(xiv) x²y(x-z) + y²x(z-x)

= x²y(x-z) - y²x(x - z)

= (x²y - y²x) (x - z)

Hope it's helpful for you!
