Asked by Jasmine

let f(x)=-2x+4 and g(x)=-6x-7 find f(x)-g(x)

please help me with the steps? I'm so confused..
Answered by Reiny
really quite simple, just subtract them

f(x) - g(x)
= -2x+4- (-6x-7)
= -2x+4 + 6x+7
= 4x + 11
Answered by Jasmine
f(x)-g(x)= -2x+4-(-6x-7)
12x+14+24x-28

-12x+14 is this the right answer?

No, Jasmine
I gave you the solution and the answer.

Wait but 2x -(-6x) would be 8x

Is Reiny right?

Hey ya'll, here's an explanation. Jasmine wasn't correct because she multiplied the terms. The question is simply asking for f(x)-g(x), just simple subtraction. Meaning they are asking for (-2x+4) - (-6x-7). For this question, you would distribute the negative sign in the middle of the two terms to -6x-7. So you would get -2x+4+6x+7. Then you would just add like terms, -2x+6x=4x and 4+7=11. So the answer would be 4x+11.

Hope this helps :)

Hey I hope this helps but the answer is
Given f(x) =-2x+4
g(x)=-6x-7
To find
= f(x) - g(x) = (- 2x + 4) - ( - 6x - 7) = - 2x + 4 + 6x + 7 = - 2x + 6x + 4 + 7 = 4x -11

Alright, so Reiny is correct. Let me explain

f(x)-g(x) are the two terms put together we're just plugging the two terms into f(x)-g(x)

So we plug it in (-2x+4)-(-6x-7)
Remove unnecessary parentheses
-2x+4-(-6x-7)

When there is a - in front of an expression in parentheses, change the sign of the term of the expression in the parentheses and remove the parentheses.

-2x+4+6x+7

Collect like terms.
-2x+6x=4x
6+7=11

4x+11

that is your answer 4x+11
