The volume in cubic feet of a workshop's storage chest can be expressed as the product of it's three dimensions: V(x) = x^3 - 3x^2 - x +3. The depth is x + 1 Help find a.) Find linear expression with integer coefficients for the other dimensions. b.) If the depth of the chest is 6 feet, what are the other dimensions. Please Help me and show your work.
oh you know synthetic divison
if you have one of the roots you can divide into the polynomial to get a quadratic and solve that
No, I really dont know how to do synthetic divison :/
well since x + 1 works we should try putting -1 in
\[(-1)^{3} - 3(-1)^{2} - (-1) + 3 = 0\]
c0=f(-1)=0 c1=f'(-1)=8 f_L(x)=8(x+1)
Which is that for a or b ?
a+b(x+1) so a=0 and b=8
I mean there is two questions, question a and b. I needed both of them explained to me.
