Question

Subtract a first degree binomial from a second degree trinomial.

Answer 1

ax^2 +bx +c -(bx +c) maybe this?

Answer 2

\[ax^2 + bx + c - (bx + c)\] would be your answer I believe.

Answer 3

looks good

Answer 4

Let
\[p_{1}(x)=ax^2+bx+c\]
\[p_{2}(x)=dx+e\]
\[p_{1}(x)-p_{2}(x)=\Delta p(x)=ax^2+bx+c-(dx+e)=ax^2+(b-d)x+(c-e)\]
Special Case:
When
\[d=b, e=c\]
\[\Delta p(x)=ax^2+(b-b)x+(c-c)=ax^2+0x+0=ax^2\]

capital Greek letter delta is frequently used to denote a change in 2 quantities
I've p(x) as a way to denote polynomials
It's another way of writing things, you'll learn along
