The way to solve this is simple subtraction of like terms after dealing with the negative.
-4x-5-(3x-2)
flip the signs associated with the negative (which is technically a -1)

-4x-5+3x+2
-4x + 3x = -1x=-x
-5+2= -3

-x-3

Determine g(x + a) − g(x) for the following function.<br> g(x)=-5x^2-3x+2<br> g(x + a) − g(x)= ?

Sonja [21]

Easy
g(x+a)
sub x+a for every x in equation

g(x+a)=-5(x+a)^2-3(x+a)+2
g(x+a)=-5(x²+2xa+a²)-3x-3a+2
g(x+a)=-5x²-10xa-5a²-3x-3a+2
so now minus g(x)

g(x+a)-g(x)=
-5x²-10xa-5a²-3x-3a+2-(-5x²-3x+2)=
-5x²-10xa-5a²-3x-3a+2+5x²+3x-2=
-5x²+5x²-10xa-5a²-3x+3x-3a+2-2=
-10xa-5a²-3a

g(x+a)-g(x)=-5a²-10xa-3a
