(4+x)^3 2. (3x+4)^3 3. (2+2)^5 4. (3x+5)^4 Answer by checkley71(8403)   (Show Source): You can put this solution on YOUR website!4+x 4+x multiply ------------------ 16+4x+4x+x^2 combine like terms 16+8x+x^2 4+x multiply -------------------------- 64+32x+4x^2+16x+8x^2+x^3 combine like terms 64+48x+12x^2+x^3 --------------------------------------- I solved the first now you tackle the rest.
