Question

Multiply (2x² +3 y²) by (5x² - y²)​

Answer 1

Step-by-step explanation:

2x square = 2x * 2x =4x

3y square = 3y * 3y = 9y

5x square = 5x * 5x = 25x

y square = y*y = 2y

now the equation is

(4x + 9y) * (25x -2y)

Now we will open bracket

4x + 9y * 25x -2y

Now we will join the variable X and y

4x +25x +9y -2y

29x + 7y
