Question 170736
When nature calls, don't put her on speaker




{{{b^2 - 6b - 2}}} Start with the given expression.



{{{(-5)^2 - 6(-5) - 2}}} Plug in {{{b=-5}}}.



{{{25-6(-5)-2}}} Square {{{-5}}} to get {{{25}}}.



{{{25+30-2}}} Multiply {{{-6}}} and {{{-5}}} to get {{{30}}}.



{{{53}}} Combine like terms.



So {{{(-5)^2 - 6(-5) - 2=53}}} which means that {{{b^2 - 6b - 2=53}}} when {{{b=-5}}}
