Integrate (2x-1)dx
will give you
(2x^2)/2-1x+c
(2x^2)/2 -1x + c (remember the constant)
_____________________
Introduction to integration:
The rule for differentiation is given as:
y=x^n > dy/dx=nx^n-1
Reversing this gives you the rule for integration:
Integrating x^n with respect to x gives (x^n+1)/(n+1) + c
You may find it helpful to remember the rule as:
"Add 1 to the power and divide by the new power, then add a constant."
So 1 will go to 1x
So 1^2 will go to (1^3)/3
So 1^3 will go to (1^4)/4
and so on....
REMEMBER THE ARBITRARY CONSTANT C

â«x^n(dx)=(x^(n+1))/(n+1)+c
â«(2x-1)dx=
((2x^2)/2)-((1x^1)/1)=
(x^2)-x+c
