Find the LCM: . r2+16r+64,r2+8r\displaystyle r^2 + 16r + 64,\quad r^2 + 8rr2+16r+64,r2+8r Click to expand... Factor: r2+16t+64=(r+8)2r2+8r=r(r+8)\displaystyle \text{Factor: }\;\begin{array}{ccc}r^2 + 16t + 64 &=& (r+8)^2 \\ r^2 + 8r &=& r(r+8) \end{array}Factor: r2+16t+64r2+8r==(r+8)2r(r+8) Then: LCM = r(r+8)2\displaystyle \text{Then: } \;LCM \;=\;r(r+8)^2Then: LCM=r(r+8)2
