Question 289108
{{{-3x^2}}} Start with the given expression.



{{{-3(-6)^2}}} Plug in {{{x=-6}}}. In other words, replace 'x' with -6.



From here, we just follow the order of operations.



{{{-3(36)}}} Square -6 to get {{{(-6)^2=(-6)*(-6)=36}}}



{{{-108}}} Multiply -3 and 36 to get -108



So {{{-3(-6)^2=-108}}}. This means that {{{-3x^2}}} when {{{x=-6}}}
