Just a question, I cant seem to solve this.

 

Find the constant coefficient when the polynomial $3(x - 4) + 2(x^2 - x + 7) - 5(x - 1)$ is simplified.

\(\text{Just add up the constant terms...}\\ 3(-4) + 2(7) - 5(-1) = \\ -12 + 14+ 5 = 7\)

Thank you, I didnt really get what a "constant coefficient" was, but realized its basically the same thing as a coefficient.

I do not think it should even be called a constant coefficient.  I think it is just a CONSTANT.

 

A coefficient is attached to a pronumeral, like in 3y  the 3 is the coefficient.

But a constant is by itself and usually tacked on the end.
