Explicação passo a passo:

\left(-x-8\right)\left(-x-2\right)\\\\\mathrm{Aplique\:o\:metodo\:FOIL}:\quad \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd\\\\\left(-x-8\right)\left(-x-2\right)=-x\left(-x\right)-x\left(-2\right)-8\left(-x\right)-8\left(-2\right)\\\\-x\left(-x\right)-x\left(-2\right)-8\left(-x\right)-8\left(-2\right)\\\\Simplifica\\-x\left(-x\right)-x\left(-2\right)-8\left(-x\right)-8\left(-2\right)\\x^2+10x+16\\\\

conta curta

\left(-x-8\right)\left(-x-2\right)\\-x\left(-x\right)-x\left(-2\right)-8\left(-x\right)-8\left(-2\right)\\x^2+10x+16
