Combine the like terms.

-3x^2 - (-x^2) = -3x^2 + x^2 = -2x^2

4x - (-4x) = 4x +4x = 8x

The difference would be: -2x^2 + 8x - 1

Answer:

[tex]-2x^{2} +8x-1[/tex]

Step-by-step explanation:

Hello, I think I can help you with this

Step 1

let's remember some properties:

sign product

[tex](+)*(+)=(+)\\(+)*(-)=(-)\\(-)*(+)=(-)\\(-)*(-)=(+)[/tex]

Step 2

when you add similar terms you must be sure to add terms with the same variable (x) and the same exponent

let

[tex]-3x^{2} +4x-1-(-x^{2} -4x)\\-3x^{2} +4x-1-(1)*(-x^{2} )+(-1)*(-4x)\\-3x^{2} +4x-1+x^{2} +4x\\organize\ and\ combine\ similar\ terms\\\\-3x^{2} +x^{2} +4x+4x-1\\-2x^{2} +8x-1[/tex]

I hope it helps, have a great day
