Find all solutions to (x+5)(2x-3). Explain or show your reasoning.

First you do x multiply 2x to get 2x^2
then you do x multiply-3 to get -3x
then 5 multiply 2x so you get 10x
then you do 5 multiply-3 to get -15

then you join it together to get
2x^2+10x-3x-15
then simply to get 2x^2+7x-15
and that should be your answer

Iam pretty sure its a sorry if im wrong
