Modeling Unit Costs with Quadratic Equations

A cost estimator is using the equation (3x8)(x1)=3x(3x - 8)(x - 1) = 3x to model the unit cost of a manufactured part, where xx represents the production batch size in thousands. Recall the algebraic steps required to prepare this equation for factoring. What is the standard form (ax2+bx+c=0ax^2 + bx + c = 0) of this equation after the binomials are expanded and all terms are grouped on one side?
