Finding Max Deflection of Beam with Bending Curve Eqn

[teng125]

if i have a bending curve eqn of w'(x) = (q/6)<x-l>^3 - ql/4 <x-0>^3 - 3ql/4 <x-l>^2 + (9ql^3)/24

suppose to find the deflection of maximum of the beam, we have to set w'(0)=0 .Am i right??

then if it is right,how can i find the value for x on which the max bending occur because i don't know how to factorize the heaviside function such as <x-l>^3


anybody pls help
thanx
