Question

How to evaluate quadratic functions?
If the given is a(x)=3x+6 and c(x)=x^2-7x+8
Then how do I evaluate a(x)-c(x)?

Answer 1

subtract
\[\huge\rm \color{Red}{a(x)} -\color{blue}{ c(x)}\]
a(x) =3x+6
so replace a(x) with 3x+6 \[\huge\rm \color{reD}{(3x+6)}-\color{blue}{(x^2-7x+8)}\]

Answer 2

first distribute 2nd parentheses y negative one and then combine like terms

Answer 3

do I completley solve the problem or do i leave it alone after that

Answer 4

then leave it alone u just have to subtract both functions that's it

Answer 5

first distribute 2nd parentheses y negative one and then combine like terms
that's it

Answer 6

\[-x^2+10x-2\] right?

Answer 7

i just want to ask `one` question just one
how did you get 10x ???

Answer 8

7x and 3x?

Answer 9

i combined them .

Answer 10

looks good right good job!
