Question 1180342
<pre>
Greenestamps made an arithmetic error on d.

Or you could muliply it out and find b and c as well.

{{{3(x-2)(x+3)(x-4)}}}

Multiply the last two binomials:

{{{3(x-2)(x^2-x-12)}}}

Multiply the binomial and the trinomial:

{{{3(x^3-x^2-12x-2x^2+2x+24))}}}

Combine like terms:

{{{3(x^3-3x^2-10x+24))}}}

Distribute the 3:

{{{3 x^3 - 9 x^2 - 30 x + 72}}}

Compare to 

{{{ax^3+bx^2+cx+d}}}

{{{matrix(1,7,

a=3,",",b=-9,",",c=-30,",",d=72)}}}
