Step-by-step explanation:
5x ^2 - 3x + 8 - (3x ^2 -7x + 4)
Distribute the minus sign
5x ^2 - 3x + 8 - 3x ^2 +7x - 4
I like to put them vertically
5x ^2 - 3x + 8
- 3x ^2 +7x - 4

2x^2 +4x +4
Answer:
Original Number = let we assume it is x
Number after decremented = y = 60
Total decrease = z = x-y = x-60
% of decrease = ((x-60)/x)*100 = 7.3
(x-60)*100 = 7.3x
100x -6000 = 7.3x
100x-7.3x = 6000
92.7x = 6000
x = 6000/92.7 = 64.73
Original Number = 64.73
