Expand products of three binomials in the form (x + a)(x + b)(x + c) John is expanding these three brackets:
\(
(x+5)(x-3)(x+6)
\)

He finds it helpful to split the first bracket and view the problem as follows:
\(
x(x-3)(x+6)+5(x-3)(x+6)
\)

He expands the brackets further. Before he simplifies, what are the terms than contain an \( \boldsymbol{x}^{2} \) ? \( \begin{array}{l}+6 x^{2} \\ +3 x^{2} \\ +5 x^{2}\end{array} \)
