See the entire solution process below:

To multiply this expression you need to multiply every term in the parenthesis by $color(red)(7c)$

$color(red)(7c)(5 - y + 4y^2$ becomes:

$(color(red)(7c) xx 5) - (color(red)(7c) xx y) + (color(red)(7c) xx 4y^2) ->$

$35c - 7cy + 28cy^2$

Or, writing it in standard form:

$28cy^2 - 7cy + 35c$

How do you multiply 7c(5-y+4y^2)7c(5-y+4y^2)?
