First we should get rid of the parenthesis
So for 2x (5x +3) do 2x Times 5x And 2x Times 3 which will get you 10x^2 (10x squares) + 6x. Then do the same to the another set of numbers so 7 x 5x = 35x And 7 x 3 = 21. so then combine all the numbers and u get 41x + 21 + 10x^2

Hey there! :)

2x(5x + 3) + 7(5x + 3)

Simplify.

(2x · 5x) + (2x · 3) + (7 · 5x) + (7 · 3)

Simplify.

10x² + 6x + 35x + 21

Add like terms.

10x² + (6x + 35x) + 21

Simplify.

10x² + 41x + 21

This is our final answer. I hope this helped!
