(3x + 4)(x – 1) + 6(2x + 4)
When I try to evaluate, the answer
keeps coming up as simplified only.
3x^2+13x+20
If I am evaluating this, how are the steps..

In order to evaluate your expression you have to know what it equals numerically. Otherwise you've gone about as far as you can go.

(* means multiply)
let's start with (3x + 4)(x-1).. use the FOIL method (First, Outside, Inside, Last) in other words...
3x*x -3x +4x -4.. ok, that simplifies to 3x^2+x-4...
ok, the rest of the problem is 6(2x+4).. you just distribute the 6
6*2x+6*4, which is 12x+24.. now add the rest of the problem i did earlier....
3x^2+x-4+12x+24... just simplify
3x^2+13x+20
there you go hope this helps!

3x(y - a million) (exchange -3 for x and four for y) 3(-3)(4 - a million) 3(-3)(3) -9(3) -27 <=== The made from 2 times a selection and fifteen = 15(2x) = 30x <=== y = 3 has a slope of 0 <===
