Question

(2x²-5y²)×(x²+3y²) find products
​

Answer 1

Step-by-step explanation:

(4x² - 3y²) : (2x² + 5y²) = 12:19

19(4x² - 3y²) = 12(2x² + 5y²)

76x² - 57y² = 24x² + 60y²

52x² = 117y²

x²/y² = 117/52

x²/y² = 9/4

x/y = ±3/2

x : y = 3 : 2

or

x : y = -3 : 2

Answer 2

Answer:

$2 {x}^{4} \times - 5 {x}^{2} {y}^{2} \times 6 {x}^{2} {y}^{2} \times - 15 {y}^{4}$
