Foil the equation if you don't know what foil it multiply the First Outer Inner and Last terms within each parentheses and then simplify.
After you foil you will get c²+4c+4-1.
Then just simplify again and you will get c²+4c+3
(c+2)^2 -1
factor completely
(c+2)(c+2) -1
i don't know what to do next. Can you help me please thank you
