It depends. Everyone have there own preferences . I myself use the completing square method because I can do it fast. But many of my colleagues use quadratic formula. so there is no such thing as which one is easier.
Solve x2−6x−3=0
x2−6x=3
x2−6x+(−3)2=3+9
(x−3)^2=12
take square root on both sides
x−3=±12
x= 3 ±2√3
If 60% of fruits are durians then there’s 40% that are not, right?
so if we have 60% of the REMAINING fruits that are mangos then we know that there will be 60% of 40%
of the total number that are mangos. this means that there will be 40% of 40% the total that are NOT mangos or durians.
the rest are watermelons and there are 112 watermelons so 40% of 40% is 16% of the total is 112.
since the durians are 60% of the total then there are 112 x 5 durians = 560
