Question

(5x-3y+2) (5x+3y+2) solving for this equation

Answer 1

Step-by-step explanation:

1.1 Evaluate : (5x+3y)2 = 25x2+30xy+9y2

1.2 Evaluate : (5x-3y)2 = 25x2-30xy+9y2

Final result :

60xy

Answer 2

Step-by-step explanation:

(5x - 3y + 2) (5x + 3y + 2)

Let 5x + 2 be a.

= (a - 3y)(a + 3y)

= a² - (3y)²

= (5x + 2)² - 9y²

= 25x² + 20x + 4 - 9y²
