Answer:
[tex]40c^{2}[/tex] -123c + 23
Step-by-step explanation:
1. First you need to distribute the negative sign to the second binomial
(23 - 8c) - (5c - 1)
(23 - 8c) (-5c + 1)
2. Distribute each term in the first binomial to each term in the second binomial, FOIL (first, outer, inner, last)
(23 - 8c) (-5c + 1)
-115c + 23 + [tex]40c^{2}[/tex] -8c
3. Combine the like terms
-115c + 23 + [tex]40c^{2}[/tex] -8c
[tex]40c^{2}[/tex] -123c + 23
hope this helps!
