Question

multiply (2x+y) (5x+3y)​

Answer 1

Answer:

(2x + y)(5x + 3y) = 10x^2 + 5xy + 6xy + 3y^2

                          =  10x^2 + 11xy + 3y^2

Answer 2

Answer:

10$x^{2}$ + 3$y^{2}$ + 11xy

Step-by-step explanation:

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

10$x^{2}$ + 6xy + 5xy + 3$y^{2}$

10$x^{2}$ + 3$y^{2}$ + 11xy
