See a solution process below:

To multiply these two terms you multiply each individual term in the left parenthesis by each individual term in the right parenthesis.

$(color(red)(3c) - color(red)(5))(color(blue)(c) + color(blue)(3))$ becomes:

$(color(red)(3c) xx color(blue)(c)) + (color(red)(3c) xx color(blue)(3)) - (color(red)(5) xx color(blue)(c)) - (color(red)(5) xx color(blue)(3))$

$3c^2 + 9c - 5c - 15$

We can now combine like terms:

$3c^2 + (9 - 5)c - 15$

$3c^2 + 4c - 15$

How do you find the product (3c-5)(c+3)(3c-5)(c+3)?
