Question

(3x+5y)^2-30xy=9x^2+25y^2

Answer 1

Answer:

(3x + 5y)² - 30xy = 9x² + 25y²

9x² + 25y² + 30xy - 30xy = 9x² + 25y²

= 0

Answer 2

Answer:

hello Frnd☺

here we can use

{(a + b)}^{2} = {a}^{2} + {b}^{2} + 2ab(a+b)

2

=a

2

+b

2

+2ab

(3x + 5y)^2 - 30 xy

= 9x^2 + 25y^2 + 30xy - 30xy

= 9x^2 + 25y^2

So both become equal so answer is 0.
