Question

find the product of (2x+5y) (2x+3y)​

Answer 1

Answer:

4x^2 + 16xy + 15y^2

Step-by-step explanation:

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

Formula / Identity : -

( p + a ) ( p + b ) = p^2 + ( a + b )p + ab

Here,

p = 2x

a = 5y

b = 3y

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

= ( 2x )^2 + ( 5y + 3y ) 2x + ( 5y ) ( 3y )

= 4x^2 + ( 8y ) 2x  + 15y^2

= 4x^2 + 16xy + 15y^2
