Computing an integral by substitution is the reverse of the chain rule for computing the derivative. Substitution is intended to rewrite a complicated-looking integral involving the derivative of some component expression as another much simpler integral. For example, if 
, then 
and
###
Integration by parts is the reverse of the product rule for derivatives:
Integrating both sides with respect to 
gives

Personally, I think the best way to grasp the idea behind the two methods is to practice. You start to notice patterns to the point where knowing which is the "right" method to use becomes second nature.
Use quadratic formula
if you had ax^2+bx+c=0, then
x=
a=1
b=?
c=34
subsitute
=5+/-3i
=5+/-3i
make 5+/-3 into fraction over 2,(10+/-6i)/2
=(10+/-6i)/2
multiply both sides by 2
=10+/-6i
we conclude that -b=10
b=-10
ok so equaton is
x^2-10x+34
Answer:
There are 260 seats in economy class and 100 seats in business class
Step-by-step explanation:
To solve this problem we first have to calculate the fraction of economic and business seats with respect to the total
We are told that every 13 seats in economy class there are 5 seats in business class
13 + 5 = 18
This means that if there are 18 seats 13 will be economic and 5 business
economic seats = 13/18
business seats = 5/18
To find out the number of seats in the airplane of each class, we have to multiply the total number of seats by these fractions
economic seats = 360 * 13/18
economic seats = 260
business seats = 360 * 5/18
business seats = 100
