So using the distributive law you get this:(2)(x)(x)+(3)(x2)(x)Since it doesn't matter in what order you multiply, let's start by multiplying the x's in the first term. So we have this:(x1)(x1)=x1+1What equals this:x1+1=x2 Now we need to multiply by 2.(2)(x2)=2x2Now we need to find out what this is:(3)(x2)(x)Again start with the x's. So we have this:(x2)(x1)=x2+1Which equals this:x2+1=x3Now we need to multiply by 3.(3)(x3)=3x3So our answer will be this:2x2+3x3 thats wut im guessin
