Seven thousand, eight hundred and ninety one
7000+800+90+1
The answer is D............
You need to move your contents e.I. 3,4,5 and your variables e.I.2x, 5y, 2z first
(f-g)(x) will be 3x^2 -2x+4 -(5x^2+6×-8)
distribute the -sign, gives us
3x^2-2x+4-5x^2-6x+8,
now combine like terms and should get,
-2x^2-8x+12,
final answer,
(f-g)(x)= -2x^2-8x+1×,
hope it helped,
good luck
