Question

Find the difference.

(4x^2 - 6x + 8) - (3x^2 - 6x + 2)

I got x^2+12x+6

can someone tell me if I got this right? If I didn't what did I do wrong, and what is the correct answer?

Answer 1

@phi @amistre64 @jdoe0001

Answer 2

I think its either x^2 -12x +6 or its x^2 + 0x +6 .. because im not sure if you do -6 minus -6 or -6 minus 6 .. cant remember of you bring both signs with it.

Answer 3

\(\bf (4x^2 - 6x + 8) - (3x^2 - 6x + 2)\implies 4x^2 - 6x + 8 - 3x^2 + 6x - 2\\ \quad \\
{\color{blue}{ 4x^2 - 3x^2}} {\color{red}{ + 6x- 6x}} - 2+ 8\)

Answer 4

So I ment to put x^2-12x-6

Answer 5

\(\bf - (3x^2 - 6x + 2)\implies {\color{red}{ -}}3x^2{\color{red}{ +}}6x{\color{red}{ -}}2\)

Answer 6

@jdoe0001 I don't understand, is the answer x^2-12x-6? thats what I got

Answer 7

\(\bf (4x^2 - 6x + 8) - (3x^2 - 6x + 2)\implies 4x^2 - 6x + 8 - 3x^2 + 6x - 2\\ \quad \\
{\color{blue}{ 4x^2 - 3x^2}} \cancel{{\color{red}{ + 6x- 6x}}} - 2+ 8\)
