I am waiting on you no multiply when we distribute we multiply what is outside by what is inside

7. anonymous

|dw:1433112384166:dw| now what?

group like terms that should be -10x + 9x the 2 terms in the middle can always be added

17. triciaal

so to use the distributive multiply each term inside by what is outside for factors we are applying this twice we can always add like terms from this was developed the acronym FOIL

for the 2 middle term they are like terms to simplify just add them look again at the detailed response -5 + 20 = -15

37. anonymous

38. triciaal
