X^2+4x-12=0
x^2-2x+6x-12=0
x(x-2)+6(x-2)=0
(x-2)(x+6)=0
x=-6 and 2
If he had to lower it by 25%, it currently weight 75% of its original weight so if we let w=original weight:
w(75/100)=30 multiply both sides by 100
75w=3000 divide both sides by 75
w=40
So the original weight of the luggage was 40 kilograms.
