Math homework help.?

A function f(x) is defined as


f(x) = xcubed -7xsquared + 4x +32





i found the factor of f(x), it's x-4 then the next question says...


hence express f (x ) as the product of a linear factor and a quadratic factor (in the form)


f ( x) = (x+A) (xsquared + Bx + C)





need desperate help or imma bout to shoot my math teacher

Math homework help.?
Its just a matter of dividing x^3 - 7x^2 + 4x + 32 by the factor x-4. You have to use the process of long division and you get :





f(x) = (x - 4) (x^2 - 3x -8)





that's it!
