a quadratic with a leading coefficient of 48 that factors

Question

It has to be an equation also it cannot be prime 

Answer 1

Easy enough - use the factored form of a quadratic:

 

y = a(x-p)(x-q)

 

a is the leading coefficient and must be 48.  p and q are real numbers; you can pick any values you want.  Multiply it out if you want it in standard form.
