I cannot figure out why I keep getting this error:

??? Error using ==> fzero
FZERO cannot continue because user supplied function_handle ==> @(Velocity)(0.5*C_D1*p*A_o*(Velocity^2)*((1000^2)/(3600^2)))+F_grav+F_rolling+Force_Car
failed with the error below.

Error using ==> plus
Matrix dimensions must agree.

here is part of my code:

fun=@(t)8*x*(t^2)+Growth+Length+Width
x = fzero(fun,1)

Where growth, length, and width are the result of other equations in my code. I have this code in a for loop to find the value at which this function is zero at 30 different values for a particular parameter that each equation is dependent upon. What am I doing wrong?
