Problem
Multiply. \[ (c-3)(6 c+1) \] Simplify your answer.
Solution
Step 1 ：(c-3)(6c+1) = c(6c+1) - 3(6c+1)
Step 2 ：c(6c+1) - 3(6c+1) = 6c^2 + c - 18c - 3
Step 3 ：6c^2 + c - 18c - 3 \Rightarrow 6c^2 - 17c - 3
Step 1 ：(c-3)(6c+1) = c(6c+1) - 3(6c+1)
Step 2 ：c(6c+1) - 3(6c+1) = 6c^2 + c - 18c - 3
Step 3 ：6c^2 + c - 18c - 3 \Rightarrow 6c^2 - 17c - 3
