Expand products of three binomials in the form (x + a)(x + b)(x + c) Ori is expanding these three brackets:
\(
(x+2)(x-4)(x-7)
\)

He finds it helpful to split the first bracket and view the problem as follows:
\(
x(x-4)(x-7)+2(x-4)(x-7)
\)

He expands the brackets further. Before he simplifies, what are the terms than contain an \( x^{2} \) ? \( \begin{array}{l}+7 x^{2} \\ +4 x^{2} \\ +2 x^{2}\end{array} \)
