$\huge \clubs \: \: \rm Answer :$

(5x + 3y)² =25x² + 9y² + 30xy

Step-by-step explanation:

$\huge \clubs \: \: \rm Question :$

What is the square of 5x + 3y

$\huge \clubs \: \: \rm Knowledge \: \: Required :$

• (a + b)² = a² + b² + 2ab
• (a - b)² = a² + b² - 2ab
• a² - b² = (a + b)(a - b)

$\huge \clubs \: \: \rm Solution :$

(5x + 3y)²

Here ,

a = 5x

b = 3y

(5x + 3y)²

= (5x)² + (3y)² + 2 × 5x × 3y

= 25x² + 9y² + 30xy

$\huge \clubs \: \: \rm Answer :$

(5x + 3y)² =25x² + 9y² + 30xy

❤️ Happy Studying ! ☺️

Answer 2

Answer:

(a+b)²=a²+b²+2ab

(5x+3y)²=(5x)²+(3y)²+2(5x)(3y)

=25x²+9y²+30xy
